TPND, I am sorry that you are having a hard time! You are the child in this family, why are you the one who is responsible for the health of this family? Your adoptive parents are the ones who had the power while you were a child. The health of your family was in their hands. It was never in yours.

Please don't see "set backs" as failures! Life is not supposed to be free and easy. Why do you want to see normal life ups and downs as your failures?
