Please help

I think I may have an eating disorder… I am 19, 5 4', and [edited by 24Help1 5/24/20 for listing weight]. All my life I've done ballet and I've been told all my life I need to be skinny and that I have the perfect body for ballet. But to my parents I'm always either too skinny or not skinny enough. I've always felt pretty insecure about my body because of ballet and my parents and people talking about me. I find myself not feeling good enough to eat when I'm really upset and I find myself being okay with skipping meals. Recently I went through a break up which is a whole other story. I've been really hurting and I found myself skipping a lot of meals again. I don't know what to do or if I have a problem that I need to address
