Hi, I'm really sorry you had to go through all that. But I'd say that it would be a really good start to get some support to help you with what you've been through, whether that's through your doctor making a referral, a support group or a charity/organization.
As for establishing YOUR identity though, at least that can be more in your hands now. You do know the abuse was about them, NOT you don't you? So whatever you did/whoever you were you DID NOT deserve that. NO-ONE is ever that bad/wrong so NEITHER were you. And I'm guessing you were abused for the slightest thing??? so HOW can that make you bad/wrong??
Now you have the chance to bring out the parts of you that you were maybe afraid to show before?? and begin to reflect on/experiment with who you want the new/free you to be. Of course, that's probably going to be a lot easier said than done, but with support you may be able to separate yourself more from what has happened to you.
Now I may be misreading the reversing what you've learnt bit but I'm thinking it may be a bit easier on you in challenging where those things came from, putting them back where they belong and replacing them with more reality based facts/recognition of things as they are. And those ARE naturally going to be a lot more favorable towards your looks, personality, talent......And you KNOW deep in yourself that you ARE more than what you've been told you are, you ARE a much better judge of value than they were.
And as for your counselor saying there isn't anything wrong with you, well I'd say that going through something like that is going to have an effect on ANYONE. So, yes, get the help and support you need AND deserve to get through this and to see the person who has SO much value underneath all of this clearly for yourself.
Best wishes
Alison
