How do you mend an estranged family relationship?

I don't think you should try to prove anything to anyone! I was in a similar situation...sorta...anyway...I stopped trying to explain my health to everyone because it just made me feel worse about myself...who the ____cares what they think? distance yourself for a while...maybe even a long while. be the best you that you can and focus on what it is that makes you happy. As long as you're not asking them for help then so what??? seriously. You know that old saying..."you'll need me before I'll need you!"...well that's usually true...they will come running to you sooner than later if you turn away from trying to prove yourself to them! good luck and try to stop worrying...it'll only exacerbate your illnesses.
