I am worried my friend is suicidal and depressed. how do i confront her about it?

Get help: She needs immediate psychiatric help. Talk to her doctor immediately to him aware of this . If necessary contact the suicide hotline for immediate assistance. Don't delay another second.

Call for help.: You should encourage your friend to get help asap. If she refuses and is threatening to harm herself, and you are in fear for her life, then you should call 911. The police, paramedics or a mobile psychiatric emergency team will evaluate her for urgent hospitalization.

Be a Friend: Don't condemn her. Be a friend and listen more than talk. Show her that she is a valuable person to you and she can rely on you to listen to her. The only advise to give her is that chemical imbalance in the body can cause her to view things in their worst conditions blocking correct responses. This means that she needs to get a doctor to assist her in this chemistry balance.
