Brokenfriend,

I'm on a board that deals with advice for troubled relationships. Once again I hate to sound negative but the advice given out the most in a situation like yours is to have no contact. Like Twinkletoes said, people like your sister can suck a person dry and wear you down. If you stay in that unhealthy relationship with your sister, you might end up just as bitter and just as angry. Is there any possibility that you could distance yourself from her for a while, just so you can experience the difference and regain your strength?
