I can completely understand. I eat for comfort as well and I am 5 days post op.
We HAVE TO break the cycle and find our comfort elsewhere or we will not be successful. I worry about this myself. It is something I was born and bred to do EAT! I finally figured out the extent to which I use food and it's scary. I WILL do whatever it takes though. I take antidepressants too, and like they all said u can't stop abruptly, this could be contributing to your anxiety.
Take a deep breath, suck on a worther's (lol they taste good, I miss that too) and know that u are worth all the effort and sacrifice.
Much love, Suzie
