Sexually abused and hiding it

I was sexually abused by a neighbor, who was also a friend of my parents, when I was about 6 or 7 years old. I've never told anyone before, even though I know that that is a huge step in recovery. When it happened I eventually took matters into my own hands by not spending the night there anymore(I was friends with his son). I've always been independent and thought that I could deal with this on my own. So I just ignored it up until last year. I had always been a little chubby, but I gained even more weight last year as I was depressed. I am trying to recover, but I just can't seem to get enough guts to tell anyone, especially my parents. My sister was also abused by the same man, but when my parents asked me if he molested me, I said no. Anyone have any suggestions to make it easier for me to talk about?
