How much truble can my teacher get into for sharing my medical info?

Im 26 years old and in school for skin care . I found out the the teacher told some new girls my medical info. She also told them that i was not in pain and that im just a drugy soooo not true. I have just recently found out that i have endometriosis and im in pain alot . I went to complain to one of the ladies in charge and she kicked me out of her office ! im so lost on this can anyone help ?
