I am bad and worthless

" I am bad or weak because I let these things happen to me. May be I deserved it"

If this is how you think, then you need to believe that it is not your fault. Someone stole your innocence, your trust, your sense of self worth.

This does not mean that you are bad or deserve what has happened to you. What it does mean is that you need help to regain your trust and your sense of self worth.
