If you are having genuine suicidal feelings, then please call your doctor or therapist or a lifeline. I think you are a pretty cool guy, and I don't want anything worse to happen to you.
If you are having the kind of "I can't take this anymore" moment (or day or week or month) that I used to have on a regular basis, you will eventually feel better. You just have to HANG ON AND KEEP TRYING. Sometimes, you just need to give yourself a break and hunker down for a little while.
Yeah, I know--no freaking help at all. But it's true.
You have unique challenges that most of us don't face, but most of us have been in a similar place, emotionally speaking. We know how hard it can be, and we are all pulling for you.
