Incest Survivors Support Group
Incest refers to any sexual activity between closely related persons that is illegal or socially taboo. Consensual adult incest is very rare. Incest between adults and prepubescent or adolescent children is a form of child sexual abuse that has been shown to be one of the most extreme forms of childhood trauma. If you or a loved one is a survivor of incest, join the group...

I knew a guy that was abused by his dad... but his dad had passed away.. the guy that I knew was asked to picture him alive and sitting right infront of him... at that time, I was actually scared of this guy... I had never seen him be so upset, but after he was done venting, he told me later that it did help... but he felt embarrassed doing it in front of others...
Later that night I heard him yelling at the wall...
I hope this helps, even a little bit.
There is a way to move past anger but it is not fun. Basically, anger is a secondary emotion. There is something underneath it. Sometimes I ask myself, "If I wasn't feeling angry, what would I be feeling?" And the feelings are worse than anger ... like powerlessness. But I guess it is more healing to feel what is inside you, because otherwise it is all frozen inside you, whereas when you feel it, as awful as it feels, it is releasing something.
