I feel the resentment and the fear, not only for your hurt, but for your niece as well. You have every right to rage, to express your anger, to feel resentment and fear. You are a survivor in the recovery path! You are expressing yourself where you have not in the past, you are releasing the sickness!
Brave survivor Goran, keep expressing yourself, keep posting, keep that little boy inside of you talking, this is healthy and productive. You have the solution, you have clues to get you to a positive resolution. You are going to a support group!?!! Yay!!!
My best to you fellow survivor!
