I believe there are forums where you can post about being suicidal--I know becuase I've seen the posts. I thought you could post about suicidal stuff here as well,

I would suggest LjadeC contacting an administrator by Private Message and asking for their feedback; I'm certain they could help you. Otherwise, try to find a forum where it doesn't say, "No suicidal posts please" at the top, and if you do find one, just the "trigger" smilie (the red one below with an X over it)...that let's others know the post could be potentially triggering for them.

Good luck, please stick around, you'll find others in the same boat as you,

***Update: Ahh, I looked and "Coping With Emotions" forum does not have seem to prohibit any type of posting.... I hope you find some relief there.
