I hate myself because I gained weight from binge eating to numb deep hurt and pain I've felt the past 2 years.
What was the pain that drove you to do this?
My boyfriend broke up with me and I was lonely and sad
I understand that must've hurt you a ton.  There are tons of better ways to cope with emotions than overeating, however, and I think you need to get some help before you seriously hurt yourself with this disorder.
Ehh, I know I should lose weight but I'd rather talk to a doctor about it.
You're right, you should talk to a doctor and get some help. I'm sure you'll be able to move on from your previous relationship over time.
