I went to sexual abuse survivor groups modeled after the AA groups for a couple years. One thing it was helpful for was destroying the sense of isolation and normalizing my experiences. The groups are free, nonjudgmental and don't require participation. I did find them quite intense though, was important to work on being grounded and knowing my limits, which I didn't at the time- that part was hard, but perhaps they'd be helpful for you. There are others for general child abuse survivors too.
