Suicide is a serious issue, here are some warning signs if someone is suicidal. The link at the bottom is the website I got this from and has more information about how to help someone who is suicidal. I stuck this under depression because suicide is a risk of depression though it can happen with other mental health issues as well. Scitzoprenia, Borderline Personality Disorder, Bipolar Disorder, etc.
Suicide Warning Signs

Any talk about suicide, dying, or self-harm, such as “I wish I hadn’t been born,” “If I see you again…” and “I’d be better off dead.”

Seeking access to guns, pills, knives, or other objects that could be used in a suicide attempt.
Preoccupation with death

No hope for the future
Feelings of helplessness, hopelessness, and being trapped (“There’s no way out”). Belief that things will never get better or change.
Feelings of worthlessness, guilt, shame, and self-hatred. Feeling like a burden (“Everyone would be better off without me”).
Getting affairs in order
Making out a will. Giving away prized possessions. Making arrangements for family members.
Unusual or unexpected visits or calls to family and friends. Saying goodbye to people as if they won’t be seen again.
