To TheBigBlue and to Tayla - please do not be sorry for posting - this is what the forums are here for.
TheBigBlue - I do think it would be helpful to have your own post, or even to copy/paste. Not necessarily because it's in the wrong thread but then we can have one that focuses on you and then even get some other support from the community. People click on this thread because it says Psychiatrist Questions but if you have your own you would probably more likely to get some extra support.
I am so sorry to hear about what you went through as a kid. It makes sense that you don't see it as abuse because it was just what you knew at the time, even if you had a sense it might be wrong. I feel frustrated your mum didn't stick up for you but I wonder if maybe it was her way of 'if I don't acknowledge it, I don't have to see how awful/disgusting/unfair it is'. I could be totally off track here, but I'm guessing the only one that might be able to offer you some insight is your psychologist.
Even if what I'm saying isn't helpful at all, I hope that you know it's okay to be here and get things off your chest. There will always be someone to listen and turn to here.
