I tried to say things before to you, that I hoped might make you feel better, or stronger, or dismissive of negative thoughts and pressures -- but I see now that you're in an extremely hostile environment. I think that you should get out of where you are, and move some place either friendlier, or where you can be without constant negative pressure.
Get out of that environment. I checked myself into the hospital a few years ago because I had become suicidal. I was doing a lot of drugs, working full time, and sleeping at best three hours a night. I experienced a period of mania, followed by a nervous break down, and found myself contemplating the best way to end my life, while trying to fall asleep on a picnic table in the park. I decided that it would be best to just check myself in to the hospital.
The real cause of my stress, and misery that led to that breakdown, and suicidal place was the hostile environment I was in, full of negative enforcement, and demotivation, and constant fighting. When I was able to get out of there, I never experienced those lows again, and hadn't before then.
If you're experiencing constant negative feedback, rejection, and people attempting to "dissuade you" by telling you what a ->-bleeped-<-ty life is in store for you, then you're in an environment that is literally going to kill you. Please, get out of there!
