I know exactly where you are coming from. I disowned my family as well. I suffered PTSD as a result of childhood abuse and it was thru cutting off contact that I finally began to heal. When I chose to no longer participate in the lies and dysfunction, my symptoms began to go away and now years later, I am symptom free. Because of my childhood, I don't form attachments, so it was easy to let go without any guilt. My own family judges me for it of course, but I did what was best for my mental health. as long as you work thru the trauma issues surrounding the abuse, I see nothing bad about cutting off contact with your abusers. I for one, consider it healthy. who needs ongoing trauma/drama in their life.
