Welcome Sundawn
My heart ached for you reading your life story.
I have the opposite problem, my adult son is treating me like your parents are treating you. IT HURTS!!!
I have to keep reminding myself they act that way because they are in a "cult"... If you haven't read Steve Hassan's books, it might help you out now. He also has a website too.
take care and hugs to you,
Codeblue
