This might sound nuts, but it also might help to really look at why you're suicidal. Something is either in your life or lacking that is making everything intolerable. Find out what that is and change it. It won't completely take away the pain, but it could make it more manageable for a while. And don't dismiss what I'm saying as "everything is awful." Okay, yeah, it probably is. But maybe your boss is killing you - get away from her, quit or transfer. You're lonely - go be around people. Find out what the worst problem is and do something about it. Even if you fail, knowing that you've tried, might be enough to hold on for a little while until some real shifts happen in your life.
