Hi bbrinadee
I am very sorry your mother treated you this way. Her behavior was definitely very abusive and hurtful. You were just a child and the words from one's parent can really hurt a child.
Based on your post it seems you've internalized your mother's negative critical voice. This is something many children who have been abused by their parents struggle with. We have a thread here about dealing with automatic negative thoughts and talking back to the inner critic that you might find helpful:
Automatic negative thoughts: Talking back to your inner critic/negative voiceIt's very hard when you continually hear things like
"I'm sorry that I had to do that but you made me act that way by... .(insert reason here)". When your mother said those things, she was basically blaming you for her abusive behavior. My own mother did similar things, like playing the victim after I got mad because she was verbally and emotionally abusive. She for instance would say something like
"Are you a good boy again?" or when confronted would act as if she hadn't done anything wrong, couldn't remember, that it was my own fault or that she for whatever reason was a victim (of life) and now I was basically re-victimizing her. These are tough things to deal with and very confusing as a child because you start to doubt yourself and wonder if you perhaps really are a 'bad' person as your mother is telling you.
But it is sad because I feel like a mother should be the person you can tell anything to. Aren't they supposed to be the one person you can always count on to be on your side?
It is sad indeed. It can be very difficult to accept that your parent has BPD because accepting this reality also means letting go of the kind loving 'fantasy' parent you never had, still don't have and unfortunately likely won't ever have. This kind of acceptance is very hard indeed. Do you feel like you've truly been able to accept the reality that your mother has BPD and what it means for the relationship it is possible to have with her? Do you feel like you've been able to let go or at least start to let go of the 'fantasy' parent?
Take care
