Lee,
Shame, as the brothers have said here, is a fact of the abuse we suffered. Believe me, it comes from a variety of sources. That we feel what was done to us was wrong, we feel our part in it was wrong (a lie the abusers are VERRRRRY good at making us believe!), we feel that we desrved it, enjoyed it, everything.
I still struggle with this (not so much by what was done to me as a child, but by what happened to me as an adult when I was subconciously "acting out"), so I don't know what else to say, but keep on telling yourself it wasn't your fault. Because IT WASN'T. It's NOT your shame to bear, it's your ABUSER'S. Not yours, NEVER WAS IT YOURS!
Someday, you'll believe it. You'll take it to heart, and it will relieve you of the pain you still feel. Until then, just knowing can be enough.
I hope you at least know it.
I look forward to hearing more from you. I'll bet you have a lot to offer. Now, with people I just meet here, I say something that might make you feel uncomfortable, but I mean it in the purest sense of the word: I love you, brother Lee, no strings attached.
Peace, my friend.
Scot
