I have been struggling with my SD almost from the beginning. Her father has always had full custody of her. I have a BD from a previous marriage as well so we were a blended family from the beginning. My SD has been in my life since she was 7 - she is now 14. Her mom isn't really in the picture as she lives in another state. Everything was great at first - back then I got along with my SD really well. My BD was 4 at the time. I found out I was pregnant a few months after we got together and since that moment she has always been hateful to me.
