Hi, I'd like to help you with your question.
I understand your dilemma. It is a very common one and you are not alone.
Here are support groups and some other resources to help you:
Adult Children of Abusive Parents: A Healing Program for Those Who Have Been Physically, Sexually, or Emotionally Abused by Steven Farmer
Toxic Parents: Overcoming Their Hurtful Legacy and Reclaiming Your Life by Susan Forward and Craig Buck
An Adult Child's Guide to What's 'Normal' by John C. Friel Ph.D. and Linda D. Friel M.A.
You can find the books on Amazon.com or your local library may have them for you.
I hope this has helped,
