Thank you for sharing your story. It hit home with me.
I saw a large portion of my family in a different light many years ago when my son and I were going through a very hard time after my Mother died. They really turned on me...and on it goes to this day. I opted to go for 'me surviving' instead of writhing in the family 'stuff'. I agree with the cyber communication comments. Keeping a safe distance from family members that can hurt you emotionally, is a good thing. But, to 'divorce' them completely could prove in the end, regretful.
