Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
From what you describe, I am almost sure it will take some intense mental health counseling. It happened in childhood, it was long term, and I agree you need to get away from these abusers. All this can be very complicated and a DS group won't really be much help (my opinion). It's going to take some serious therapy.
Here is a link of all DS Groups with a search feature. Try searching for ABUSE and I hope you find what you are looking for.
