Maybe it's a good idea to not hang around the family who says bad things about you. I also think it's a good idea to keep contact with the sister who makes you feel better. Maybe she appreciates you for who you are more?

Do you know the story of the ugly duckling? Growing up, we might not even know it's real value until we're older anyway, and by that time we may have forgotten about it. It's about a "duckling" that was very ugly, strange, and different, and spent its life abused and alone. Eventually it found out it was just hanging out with the wrong birds all along. I think it's a nice story because it reminds you that you may just be hanging around the wrong people when you are treated like an outcast.

I'm sorry you're going through this. I hope the best for you .
