Sorry you heard this and it is supsetting for you. Are you in T? Would be good to talk to a therapist about it.

I overheard one of my college roommates talking negatively about me to our resident advisor, who looked after everyone on the floor. It was very negative--obviously she didnt like me, was jealous of me, and things I was doing were irritating her. I learned to treat her better and changed my behaviour as a result of that. I didn't like hearing it, but I put it to good use. Hope you wll find a way to generate some good out of what you heard. Maybe it will be just be an understading of the limits of your parents.

I've always maintained gossip is about the gossipee, not the gossiper. In his case, what your parents said is more a reflection on them and their views, than about you. If you don't feel you are a worthless loser, then you aren't. Having them say it doesn't make it so.

Hugs to you!
