I share a room with my 9 year old sister (im 15). Today she was in there while i was changing because we were both changing at the same time. She saw my injuries and asked what happened. I told her that the dog jumped up and scratched me. She doesnt know what Si is so i dont have to worry about her being suspicious or tattleing, But what i do have to worry about is her telling people that the dog jumped up and scratched me because she has a big mouth and talks constantly. My parents think that i dont si anymore. The only people who know i do it are my therapist. And one of my friends from S.A.F.E. My psychiatrist has a pretty good idea but he doesnt know for sure because i lied to him and told him that i didnt. WHAT DO I DO?!
