I am so sorry you have had to go through this, it is so hard when family treat us so badly, it was realy awful what was done to you and being ill too its unforgivable, you sound like you are a better person and if they are willing to do this to you out of ignorance i think you are probably better off without them, it is hard losing family but if they are such a destructive pressence in your life i think you have to walk away
