Hi Hornplayer,
I'm sorry to hear about all that painful stuff you've been through

You're here and reaching out though, and that's encouraging. I hope you can feel safe enough in this place to begin talking about your thoughts and feelings. Sometimes it takes a while to get responses, but people here do care.
There are forums on this site specifically for abuse, bullying, and self harm. The one for self harm gets the most traffic.
Is there a safe place you can go to get away from the abuse (I'm not sure if it's still happening?)
Keep talking!
Blame it on me, but know that I won't regret one iota.
