I can relate. After I began getting treatment, though, I had less and less contact with one side of the family, so they didn't really get a chance to treat me worse, but they would have if I had stuck around.

Still have to deal with little digs though, like an aunt who closed an email with "Be Well" after I confronted her about something she did.

They just don't to admit anything is wrong, and if someone in the family has a diagnosis, they don't know how to deal that so they put that person down further.
