Overly controlling family

Some people who have normal families can do simple things with friends or boyfriend/girlfriends but I can’t. I can’t do anything without my step-dad seeing every single thing I do and start telling me crap about it. I think part of why I feel and think some of the things I do is because of him and my moms choices. Sometimes I want to run away, and get away from everything that’s going on. I want to hide so no one can find me. I want to tell other people about my experiences at home and what I go through, but I’m scared of their reactions. I’ve told a few people, they all say that what I’m going through is abuse, at first I didn’t realize it because it’s happened my entire life, i viewed it as something normal. But now as time progresses it really isn’t. I want to use this page to talk and express myself, maybe some people are going through the same thing I’m going through, maybe someone can help me.
