I've been there: the fighting yourself. Am prob still a bit there, but also I do fundamentally know that all that happened did actually happen.
It's amazing the level the mind goes to totally wipe out memories. But , whilst that clearly helped at the time to survive and protect the self, because it comes back in such a confusing way and because denial of reality was so complete: it then creates this total confusion about what is real, what isn't, what is a memory, what isn't, is it made up? What is it?
Thing is: no one can say. Other than you.
It just takes time to work that out.

@Survivor3 says, do you have a T? It really helped me to work it all through and build confidence in my knowledge of what happened (and then even more memories came back....)
