Suicide is the tenth leading cause of death in the United States, with nearly 45,000 Americans taking their own lives each year,according to the American Foundation for Suicide Prevention.

Suicidal thoughts and behaviors can be reduced with the proper mental health support and treatment, and are not weaknesses or flaws, the American Foundation for Suicide Prevention says on its website.

Dr. Kevin Gilliland, Psy.D., said there are several signs to look for if you believe someone you know may be or become suicidal.

“It is really difficult for most people to watch someone struggling with feelings of depression or hopelessness about life,” Gilliland previously told PEOPLE. “If you fear that a loved one is struggling with life and they just ‘aren’t themselves,’ talk to them. Try to listen more than you talk and just be curious about the change you have seen in them.”
