Yeah I have seen the damage last a long time. I see the same issues with rape victims. Had a female friend who was repeatedly raped as a kid and now over 30 she still has issues dealing with it; just talking about it is even hard for her and she went to counseling for years. I've know another one lady that basically is "bi-polar" from being molested as a kid and they feel her mental issues have a lot to do with those traumatic situations. As I said I was mentally abused as a kid and for the longest time I had very low self esteem and thought I was a ugly kid; followed me to adulthood and I have learned how to deal with those issues, but amazes me how much that affected me.
This may be the saddest part because the abuser doesn't realize they leave emotional scares that last for a lifetime.
