I can relate. I did the same thing for years. I felt like it was all my own fault and it was over and i should just deal. Since I have opened up and told some members of my family about my abuse I have been told that It happens to everyone. Well, I am through allowing anyone minimize my pain. What happened to me as a child shaped my whole life. It was not a little thing, and all brothers do not rape their sisters!
If it causes you pain, it is not a little thing.
