Abuse is abuse — and you did what you needed to do to get yourself out of there. Sadly, the protective systems have huge gaps and problems, and when you weren’t being listened to you spoke to them in a language that got you away from people who were, indeed, abusive.
I think it would be time to have both individual and group therapy. I know this may sound daunting, but the truth is the family you were born into didn’t have the skills to care for your properly. The cornerstone of group therapy is the correction of the initial family dynamics. I would look for a good therapist in your area that specializes in group therapy. They will be familiar with this process and help you use the group to rebuild your faith in people, and yourself.
