So, it has been my experience that mental health care could care less about you unless they're already cashing your checks.
Anyway, on the subject of suicide, you only get one go around on this ride. If you're seriously contemplating suicide, go see your regular doctor about it. There are great drugs out there. Yes, they can have side effects, but let's be rational here: a lack of boners, for example, is well worth it to find value in life again. If you kill yourself, everyone in your family will be devastated, your friends will miss you more than you think, and, to be perfectly honest, you still owe society for educating you and putting up with the ridiculous stuff you did as a teenager. ;-)
