Some will reach out and talk about ending their lives, while many suffer in silence.
"We move through our lives with a mask on, smiling and laughing and entertaining and dying on the inside," explains mental health advocate Terrie Williams.
Warning signs a person may be suicidal include:
-Giving away valued possessions
-Withdrawing from friends and family
-A pattern of substance abuse
-Sudden calmness, especially for someone who's attempted suicide in the past
"The most concerning is dramatic behavior changes," says Crisis Link's Laura Mayer. "If they are normally a social person and the stop being social, they start to give away things that are important, they withdraw, angry outbursts, frequent sadness. What you're looking for is the change in what their normal behavior would be."
Mayer is program director with Crisis Link. She says there are ways to help someone who is threatening suicide.
"Reach out. Call the hotlines that are available. Don't do it alone, because you can't," she says.
Family doctors have information on other suicide prevention resources and community programs.
