Permenantly excluded from 2 schools by the age of 15. I think I was probably hyper all the way back then. I was a pretty unpleasant young man and quite violent from a relatively early age. I guess some childhood sexual abuse didn't help. Serious suicide attempt at 19 (razor blade to both wrists).

It's hard to look back retrospectively, but I think both of the above incidents were red flags, but back then, things were swept under the carpet.
