I'm sorry you lost your friend. There is nothing you could have done. I have a friend that has tried to committ suicide so many times this year I've lost count. know matter how hard I've tried to cheer her up and tell that's not the way, it never stops her from trying again. I'm afraid she will one day succede and I will never even know because their is no one to one to call me.

I know you feel helpless right now. You might want check out our Grief and Loss forum. I hope someone there can help you overcome your guilt.
