This isn't a huge worry of mine but it has always been a niggle. I remember we had a thread like this a while back but I couldn't find it!
What concerns me are all the reports you see of these dreadful criminals/abusers and then the professionals saying that a lot of them were abused themselves and while every person who has been abused doesn't necessarily become an abuser, it often follows that those who do have been abused in the past themselves.
I see myself as a totally normal human being but when asked by GPs/consultants about any mental health problems in my family, I feel obliged to tell all (long history of it) and I often feel that from that point onwards, I am being looked at through different eyes (iyswim) and that really pisses me off!
