'...if I accepted the past but I'm so angry that I had the life I did.'
That kind of anger is normal and good, I think. Anger at my past helped me express some things in therapy I had been too ashamed to ever tell anyone before. Accepting that the past happened doesn't mean to excuse it, only acknowledge it in a way that allows healing to begin.
I have to think in terms of physical wounds when I try to understand what emotional wounds have done to me. If I spill boiling water on my hand it makes me pretty mad and if I don't accept it happened...well, you know.
I spent years lamenting my childhood, knowing it shouldn't have happened and I wanted those responsible to make it right. It's been over 20 years since I first confronted my mother and she has yet to accept her part in allowing the beatings.
I think acceptance of the past is something that when it comes, enables us to begin to bind up the hurt. My family sure wasn't going to do any first aid on the pain they inflicted, though I waited for it a long time. This too, is wounding from the rejection involved.
The first time I talked with my mother, at my T's instruction, about all the violence her husband had inflicted on me, my sister and brother, she said my T needed counseling. I'm pretty logical and so it was maddening trying to convince her with logical explanations, only to have her deny there was every any wrong done.
It took a while for the light to come on, to see
she didn't want to understand. I read on another thread recently about this kind of denial being the means for those who enable abusers, by sitting by silently, to avoid the fact they failed to protect us. I finally had to walk away from the toxic effects of it all.
It really is hard as you mentioned about the constant struggle, but freedom, even measures of it over time, is worth the struggle. The fact you recognize so much already about the healing you want is progress.
