I (21f) am terrified my younger brother is going to kill himself. Almost every single one of me and my 6 siblings are autistic, and so far other than my brother I've been the only one to self harm/attempt suicide. I've had a few attempts land me in hospital, but eventually kind of grew out of it oddly.

Me and his trauma is very different, most of his are related to a medical condition he has. It's non fatal and treatable, but causes him a lot of pain and he spends a lot of nights crying his eyes out and smashing up his room. He's covered head to toe in cuts. Mine were always a lot deeper, so theres some comfort in that they tend to fade a lot faster on him, but I know from close male friends and family that suicide is obviously a lot more on the table with males satistically, and I'm very worried he might go too far, on purpose or by accident.

Parents have tried taking him to therapy, but with his PDA ( Pathological demand avoidance ) and general hate for doctors/therapists/etc, that was a dead end. He also talks to a lot of older men online, his words not mine. I remember getting dragged into a lot of nasty groups at his age, I hope to god he's not bumped into anyone too bad.

I just don't want to wake up one day finding him dead.
