Binging and purging 😕

I've been vegetarian for two years and for the past year I've had this addiction to food (mostly sweets). Its gotten to the point to where it's borderline eating disorder. I don't want to self diagnose myself or anything but it's been a constant cycle of binging and purging whenever I'm alone in my kitchen. I've been a healthy weight my whole life but because of this I've gained 20-30 pounds, my self image isn't so great right now 😌. I was wondering, could arian? maybe I'm not getting enough nutrients or something? I'm still pretty young so I don't want to be ruining my body while I still have years ahead of me. I know everyone on eve isn't a nutritionist or anything but I'm not sure who to go to. Any advice is greatly appreciated
