I Have Bed, Binge Eating Disorder

F*******ck. What have I done?! It took me 3 months to lose just 14 lbs. I've now gained back 3 lbs. It was as if my mind retreated or I wasn't conscious, that I ate so much last night. As a result, I wanna throw up, purge in someway or another, or punish myself now. It's ducking ridiculous.
