Hey journey. I'm going to post a reply, don't go yet.

Okay, I was reading your post from my tablet while having a cig outside, and I rarely reply from my tablet.
My therapist told me something, and it's true, that you don't have to forgive anyone. It's a choice, and it's up to you or not. Even so, forgiving for something like childhood abuse and neglect is not remotely easy, and even if you choose to forgive, it can take years.
There's something called "abandonment depression" in psychology that I think we all have to work through at the end of the day, to recover. Working through your anger, rage, depression, grief, etc.
It's totally understandable that you have a hard time letting go, especially if no one has said sorry. I read your post about your mother, and I'm deeply sorry she had done that to you.

I would be angry too if my mother was treating me like that! Among other things.
I think the key for you is working through your anger, not necessarily not being angry, you know? Screaming at your abusers is probably not advisable, but doing something constructive with you anger, or even less destructive. Screaming into a pillow, playing a video game, listening to rock music, are some things that help me.
I totally relate to the primitive, violent rage you're describing. It almost always comes out with my mother only, the one who tormented me, smothered and then withdrew/abused me. You're not alone with that.
And, it's also very understandable that you're angry for having a personality disorder. You may feel "flawed" for having it, and angry at the people who "gave" it to you.
You WILL recover from this, though.
