Felling Helpless

No one can possibly understand because I do not look like I need to lose weight and therefore people would hate me for being ungrateful. I am 5'4" 128 lbs and I work out 6 days a week with cardio, weights and yoga. I feel stupid even writing on here because I feel like I should be happy that I am small but it's not about size. It's about the depression I feel after quitting alcohol and then trying to quit sugar for the last 6 weeks and failing (at the sugar). I feel like a crazy person. All I think about is sugar after about 12:00pm each day. It's awful. I do the food correctly but mentally I can't handle the pain of having nothing to numb me so, I binge on sugar. I used to drink about 2-3 drinks 5-6 nights a week so now that I am off alcohol, sugar addiction has become that much more apparent. I am so sick of not being in control of my life. Today I binged and then fell asleep in the middle of the day. It makes me hate myself and I feel so guilty. I started working out at the same time I quit alcohol, 6 weeks ago, and I have been binging on sugar ever since about every other day. My weight has stayed steady, but I have been an emotional wreck every day. I just don't know how to live without sugar. I feel like I am mourning the loss of a best friend so I keep hanging on for dear life even though I know it's bad for me. I wish i was stronger. I am feeling like I should just go cold turkey and get the detox over with, because I have been trying to eat sugar steadily and all I do is binge. I can't handle eating just a little bit. Any supportive comments would be helpful from you guys who have done this before because I am having a really hard emotional time right now and I don't know what to do. I feel like such a failure.
