They’re becoming more common

In the United States, suicide rates increased in 44 states from 1999 through 2016, rising by more than 30 percent in 25 states, according to a report by the Centers for Disease Control and Prevention. Reversing the trend will be tricky, as there’s no single cause for suicide, according to the American Foundation for Suicide Prevention. But knowing the suicide warning signs—which can vary from person to person—may help you save a life. As a first step, learn what psychologists wish people knew about depression.

There was an almost 10 percent increase in suicides—an additional 1,841 deaths—recorded in the United States in the four months following comedian Robin Williams’ death by suicide in 2014, according to a study in PLOS ONE. “That indicates just how powerful this kind of ‘contagion’ effect can be on a vulnerable person,” says Elizabeth Berger, MD, a child psychiatrist and author of Raising Kids with Character. When people who may be trying to manage their depression see this person they admire taking his own life, they see it as a way for them to escape their own misery. “The tragedy of Robin Williams’ death is that because he was a beloved public figure, people who were already suffering felt they had gotten permission to relieve their pain,” says Susan T. Lindau, MSW, MFA, LCSW, founder of Santa Monica Center for Acceptance & Change in West Los Angeles and an adjunct professor in the Department of Adult Mental Health and Wellness at the University of Southern California. “The voices decrying his death weren’t strong enough, persuasive enough, or prevalent enough to push those people experiencing suicidal thoughts to reach out for help.” If you’re having suicidal thoughts, don’t suffer in silence. Here are 10 silent signs you need depression medication.

They undergo drastic behavior changes

“Any significant and unexplained changes in behavior should at least be a cause for inquiry,” says Joel A. Dvoskin, PhD, a psychologist at the University of Arizona College of Medicine in Tucson. “Significant negative changes are especially concerning.” However, behavior changes don’t mean a person is going to kill himself, he says. “Ask empathic and respectful questions,” he says. “How are you doing?” is a good start, he recommends. “When the person says or does anything that suggests or implies an intention to hurt himself or others, ask whether or not the person is intending to hurt himself or anyone else, stating it in the form of a question,” he says. Doing so is neither disrespectful nor intrusive, he says. Here’s how one teen talked someone out of suicide.

They withdraw from friends or social activities

Choosing to be alone and avoiding friends or social activities can be possible symptoms of depression. Any sign that indicates loss of interest in activities the person previously enjoyed is suspicious. “Young people, in particular, like to be around their friends,” says Daniel J. Reidenberg, PsyD, FAPA, executive director of SAVE (Suicide Awareness Voices of Education). “So, when we see them pull away from peers, that’s concerning. Adults withdrawing from social activities, family activities, even going out after work with colleagues could be a sign that something is going on.” He says that withdrawal suggests the person is struggling with his thoughts and emotions. “They don’t want others to see that, so they avoid those situations,” he says. “Withdrawal also gives them time to sleep more and ruminate about their situation, which indicates they’re not doing well.” Here is the difference between social anxiety and depression.

They make plans

One of the suicide warning signs is that often, a person considering suicide will take steps to put his personal business in order. He might visit friends and family members or someone he hasn’t seen in a long time. “For some, this might seem like an effort to reconnect,” says Dr. Reidenberg. “But it could be a way to make amends before an attempt.” He may draft a will or clean up his room or home. The person may give away possessions he previously loved because he doesn’t think he needs them. Some people will write a note before committing suicide.

They lose interest in personal appearance

A person who is considering suicide might suddenly become less concerned about how he looks and neglect personal hygiene. “They’re more focused on survival than their appearance,” says Dr. Reidenberg. “They’re doing all that they can just to get through the day. Their appearance isn’t a priority.” They also have less interest in what others think of them, he adds. “They’re too miserable and too depleted to care about how they look,” says Eileen Kennedy-Moore, PhD, an author, psychologist, speaker and creator of the audio-video series from The Great Courses called Raising Emotionally and Socially Healthy KidsHere are 12 ways to help someone with depression, according to psychologists.

They’re bored by school, work or hobbies

“When someone is depressed, nothing feels good or is interesting,” says Dr. Reidenberg. “Everything is hard, exhausting, and feels bland. Accomplishments and achievements (related to school, work or interests) go away because you’re focused on your pain.” These activities feel pointless, says. Dr. Kennedy-Moore. “They also don’t have the energy to try, and they no longer find pleasure in them.” Read how acne can be a depression risk factor, especially in the first year it’s diagnosed.

They’re preoccupied with death

People who exhibit this suicide warning sign aren’t simply looking for attention. Whether it be a conversation with a friend, a writing or art assignment, or a journal entry, any expression of death should be taken seriously and seen as a red flag. They may also be researching about suicide online, asking around about how to buy a gun or where to get lethal drugs, or be interested in TV shows, movies, or songs with suicide themes, says Dr. Reidenberg. “Anyone talking about suicide—directly or indirectly—is a key warning sign,” he says. “All statements about suicide are to be taken seriously, even if someone has said it multiple times over several years.”

They start—or increase—drug or alcohol use

“Increased drug or alcohol use is not only an indicator of psychological suffering, it’s a common contributing cause of suicidal acts,” says Dr. Berger. Many people who feel anxious, agitated, or distressed turn to drugs and alcohol for relief, escape, and to feel calmer. They may not have previously abused drugs or alcohol or they may start using more of these substances. But they take these things to numb themselves and make themselves feel better. Drugs and alcohol impair judgment, and the person is more likely to make poor decisions and do something impulsive or high risk, says Dr. Reidenberg. These decisions may endanger themselves as well as others. “When someone is depressed, adding a substance to an already unhappy mind can lead him to do something fatal,” he says. “This is particularly true for someone who just starts to use alcohol or drugs when he hadn’t before, and now he’s depressed too. This behavior change is a warning sign he isn’t doing well.” Don’t miss these 7 foods that could make depression worse.

They have extreme mood swings

Excessive moodiness can be a symptom of depression and one of the suicide warning signs to watch for. Depressed individuals can go from extreme sadness to irritability to intense anger. These mood swings might be out of character, too—the person may look different and sound different, says Kevin Gilliland, PhD, a licensed psychologist, executive director of Innovation 360 and author of Struggle Well Live Well: 60 Ways to Navigate Life’s Good, Bad, and In-Between. “They’re not ‘themselves,'” he says. Mood swings can be a sign that they’re emotionally and psychologically unstable, says Dr. Reidenberg. “If these go on too long and without treatment, they can lead to impulsive behaviors that are risky,” he adds. It’s just one of 8 medical reasons why you’re always in a bad mood.

They feel like they’re a burden to others

The person might feel like he’s a major burden to his family, friends, or society. He may feel guilty about letting people down, for example. He may say things like, “Everyone would be better off without me,” or “Things will be easier without me here.” Ironically, nicer people are more prone to depression. “Be attentive to statements like that and don’t be afraid to step in and tell them they’re not being a burden,” Dr. Gilliland says.

They suffered a current loss, crisis, or problem

“Many people who attempt suicide are responding to real-life issues that appear to be insurmountable,” says Dr. Berger. Social humiliation or relationship breakups are also often the stimulus for suicide attempts, she says. Serious physical illness, loss of livelihood, homelessness, and other life losses may factor into suicides, she adds. Also look out for people saying they feel trapped or in a hole they can’t get out of, says Dr. Gilliland. “When people begin feeling a job, financial situation, or relationship is unbearable, it’s not unusual for them to become depressed or be constantly thinking about the hopelessness of the situation,” he says. “At times like that, we sometimes make up a story that the rest of our lives will be like this and we can’t fathom living like this.” Here are 9 true stories that show what people going through a loss need from you.

They have subtle signs of depression

Depression signs vary, says Dr. Berger. They include difficulty sleeping, weight loss or gain, guilt, unusual worries, irritability, sadness, anger, or hopelessness. “Of course, these are common signs among ordinary people, and not everyone with these signs is suffering from depression,” says Dr. Berger. She says that if these signs last more than a week or two, that’s a red flag that the person needs help. Note that lots of people are depressed and most don’t kill themselves, says Dr. Dvoskin. “However, even if they aren’t intending to kill themselves, people who are seriously depressed usually need help,” he says. “It might make the person angry, but he’ll be alive.” Get to know these hidden signs of depression.

They talk about suicide

Not everyone who is considering suicide will say it out loud. And not everyone who threatens suicide will follow through with it. “However, many people who commit suicide do have a history of behaviors that indicate the threat of self-harm,” says Dr. Berger. “Every threat of suicide should be taken seriously, even threats that seem harmless, exaggerated or overly dramatic.” Say this one thing, and you might talk a person out of suicide.

Err on the side of action rather than inaction

In many cases, suicide can be prevented by being alert to the suicide warning signs and intervening before the person can commit the act. People with support from friends and family and who have access to mental health services are less likely to act on their impulses than those who are isolated. Take it seriously if someone you know is threatening suicide, says the Cleveland Clinic. Don’t leave the person alone. Ask the person to give you any weapons he may have on him. Take away sharp objects or anything he might use to hurt himself. Bring him to an emergency room or call 911. “Remember that you’re not a mental health professional or a crisis response worker,” says Phyllis Alongi, MS, clinical director of the Society for the Prevention of Teen Suicide. “If you know a loved one is in immediate danger, call 911 right away.” If someone in your life struggles with depression, use these psychologist-approved ways to show you care.
