I agree with those who've already said you have to do the blaming to get to the next part.
People who grew up in 'normal' families often miss the fact that your childhood is what creates you. When you realise your family wasn't 'normal', you can't suddenly become a person like those others, because you simply lack the foundation for it. You can't go back and get another childhood, you're already the individual your family created.
Getting "past" it is an incredibly slow, arduous process and I don't actually blame people who decide not to bother (including my own parents!) I observed and mimicked people who had 'normality' as far as possible. But the underlying values, which lead people to do the 'normal' stuff without thinking, are a whole different game. I think I'll be doing well if I've learned more than half of it before I die. By way of example, I'd never experienced tenderness until I went to hospital - in my forties. Having not known it, I didn't know I was missing it. I didn't know how to give it, obviously, and had to realise that what I thought I'd been offering as tenderness wasn't, in fact, the real deal. I think a lot of mothers here may have realised something similar when they had their babies.
So, yeah, the thought process, in my case, went something like: I'm a bit odd => because my parents were incompetent => so it's their fault => the BASTARDS, look what they've lumbered me with! => er, well I can't go through life feeling like this, what shall I do about it => therapy, therapy => OK, no sense in hating them for it, they're weird and it's my bad luck => more therapy => and here I am, still learning.
Blame? Yes, because it is their fault. But I haven't got a time machine, and all parents do the best they know, even if that best is worse than useless. (It's basically the same for people who grew up caring for an incapacitated parent.) So I'll settle for regret, and get on with fixing the damage.
I didn't read your other thread. Hope I've managed to make a bit of sense.
