<human>: As the title says I am 6' and weigh 270 pounds. About 3 years ago I was in Air Force ROTC, weighed 180 pounds and could do 62 push ups in 1 minute. Then I got cut from ROTC, fell into deep depression, failed all my classes, transferred schools and gained 90 pounds.

Went to therapy, changed majors, and got on anti depressants and my life is looking up. The only problem is I can't shake my drive through habit. I will go to the grocery store, buy a bunch of healthy food that I enjoy eating. Not cook and hit a drive through. It sometimes feels like I black out, and just end up at Burger King or Whataburger. I spend so much money. 
I'm so tired of being fat. I miss being fit. I miss clothes that fit well and having more energy. I know on an intellectual level that I have just quit, but I can't. I don't know why I can't and I hate it, and that self loathing leads me back to the drive through. 
What can I do to get through the withdrawals, or do you just have to gut it out and get over it.

Summarize the given text in a few sentences.
<bot>: I'm fat. Used to be not fat. Fast food addiction prevents me from un-fatting. Help with withdrawals pls.
