I'm really sorry to hear what you went through.
I suffered during my education due to an illness... that I also got bullied over. I also contemplated suicide. I'm not at all comparing myself to you though. I'm sure yours was far worse. Autism is serious.
How ever. I am a firm believer in the best offence being a strong defence. In the end there is never a cure, and no one can say anything to make it go away. Regardless of how bad it gets, as humans, we cope with it, accept it, and keep on going. Resiliency or ignorance.
If you need help though, I suggest counselling. I went through several counsellors. The one I'm seeing at the moment is amazing, but all she's done is point out the obvious and make me realise that past is the past.
