Should I break up with her?

My girlfriend's body is triggering me (I'm also a girl, she's my first gf) because I'm relapsing hard from my eating disorder (relapsed from other stresses). She's so skinny (maybe even underweight?) and I know that won't change. Should I break up with her so my eating isn't so bad?? I'm losing weight fast and I know that will happen with or without her but every time she leaves I want to cry because I feel disgusting next to her. I love her but she makes me hate myself even more
