Bulimia and my family and boyfriend

Me and my boyfriend have dated for 6 years. We had broken up for a year for many reasons. My parents absolutely despise him. But now we are back together and stronger than ever. I am currently going to therapy twice a week for my eating disorder. My parents feel as though me and my boyfriend being together will set me back dramatically in my disorder. So they keep threatening to take everything away from me ( i am 21) such as helping me pay for college or anything else for that matter. I am stuck between a rock and a hard place. I am extremely close with my family and this is tearing us apart. However i also am absolutely positive that i am going to marry my boyfriend. We have made plans to do so. However, with my parents anger towards me; i have been falling back into my bulimic ways. It feels too overwhelming to deal with the problem. To be honest I'd rather throw up instead. I am in a loose loose situation. if i leave my boyfriend 1 ill be heartbroken ( again) and 2 i will definitely resent my parents for it. But if i stay with my boyfriend, everything is going to change and i might loose my close relationship with my family due to their hatred and lackof acceptance of my choices. I do not really have time to fiddle and play games. From my eating disorder I have "precancer" which is barrets in my case. Usually barrets eventually turns into esophageal cancer. i get endoscopies every 2 years to check up on it as of this past year. But when i throw up blood i get an endoscopy that same week. I don't know what to do because all this stress is really effecting my eating disorder. I really don't want cancer. Any advice?

Stick with your boyfriend its your life not your parents, you can take out loans for college. & find an extra Job if you need to. But if he makes you happy go for it. Your parents love you and will soon accept the fact you really want to be with this man. I wish you the best of luck!
