I'm feeling really sad and angry... when I was 6years old I got adopted by a family and when I was 12 he and his 15year old son fingered me and his son had sex with me. :*( As I grew up I could figure out what exactly happened and how to explain it.. But even though I was scared I told my family and they all turned there backs on me, two of the family members even caut his son doing it to me and they turned a blind eye. I was hurt,scared, confused, and all alone. When I turned 20 and had a place to go I left. They all send me mail blaming me, asking why I didnt yell for help... saying i ran away, and they make me feel like shit even though they were there parents and i was a child!!! I wish somone would have given me the courage to get a rape kit done so that they all knew I wasnt lying. Now that I'm about to have a baby girl of my own I'm terrified and scared for her.. of course none of that family will be in her life but there are still many people out there like that. Anyone else experienced this? Even though they didnt believe me wasn't it there job as parents to protect there kids and get me tested to see it for themselves?
