I'm sorry Melissa. I've done the waffling weight loss with anxiety and depression and I do understand.
I think what is in your favor is that you realize what you are doing. For example, I was cooking a huge pot of potatoes with butter and cheese and then eating the whole thing, knowing that I'd feel sedated and calm after that. It was really more like ill and comatose, but you get the picture.
Something you can try is to change your routine. You know you are going to crave that fast food and that Netflix so on a work day plan your meal ahead - greens and vegs and a lean piece of meat or vegs protein. Take that to work and instead of going out to your car, go to a table and slowly eat your meal there with no Netflix or book or anything that would distract you from your lunch. Then, because you will have some time left out of your lunch break, take a stroll.
I know you are anxious but if you can do this I think you can move towards breaking the chain.
