what should i do?

If you are considering suicide...

Tell someone about your feelings. Most people will want to help you, but they may not realize how you feel unless you say something.
Seek professional help. Therapists can help you see other ways to solve your problems.
If you've been in treatment before, know that a different treatment may be effective for you. Find another doctor if you need to.
Suicide is a permanent solution to a temporary problem. Set a period of time that you will wait out before hurting yourself: a few minutes, 24 hours, a week.

Some things to do if you are worried that a friend is considering suicide...

Talk with them! Mention suicide if your friend doesn't bring it up first. Talking about suicide will not cause someone to commit suicide.
If someone talks to you about suicidal feelings, take them seriously.
Let them know that you are concerned about their well-being, even if they don't want to talk to you right then.
Try to understand how they feel, but don't jump to conclusions. Listen to what they have to say.
Be direct, open, and honest.
Help them understand that depression can, and should be, treated.
Don't try to handle a crisis alone--get professional help.
Don't leave a suicidal person alone.
If you can, remove lethal means.
Call a crisis hotline.
Take your friend to the emergency room.
Don't give up after the crisis passes. Keep supporting your friend and encourage them to stay in treatment.

SUICIDE IS A PERMANENT SOLUTION TO A TEMPORARY PROBLEM.
