I been binging a lot lately and it's killing me...?

Today I just ate 4 biscuits from Popeyes that my mom bought for my brother and dad. I feel so terrible. I have lost 49 pounds since January and I remember it used to be so easy to eat healthy and exercise and now I can't see to motivate myself to exercise and I swear I eat everything insight. After I binge I don't even feel guilty but in the back of my mind I know that off I keep binging like this I know i will gain all that weight back ( I used to be 196 and know I'm 146). How do I stop!?! Please! I don't want to go back to my old weight, I used to feel so terrible back then. Help me!?!
