My only concern would be the fact that you still live with you mother. When i addressed the issue of abuse I had to take it very slowly. I had to be super careful because i still lived with my abuser, and I had to make sure it was VERY clear that I was no longer in any kind of danger. (the abuse had already ended) I think if I ever hinted that there was any kind of present risk he would immediately take action. He really needed to clearly know this before I could come out with all the details.
