Eating disorder

I have been a bulimic since I was 14 years old and I am now 23. I can't help it and I'm starting to have health issues from it. I have issues with acid reflux, and my gallblader. I told my husband last week because I want to stop and I need help. He just thinks it's stupid and doesn't get why I can't just stop. I'm not a super skinny girl I'm 5'2 160lbs so it's not like this is helping me lose weight It's just a habit. Anyone else ever dealt with this issue?
