Hi Angie. Welcome! I'm so glad you found this site!
You mentioned that you use food to comfort yourself. How do you feel after you eat this comfort food?
I struggle with the same thing. I used to get off work and eat a ton of junk to reward myself for making if through the day and deal with stress. But after eating I just felt worse, not better. It was a bad cycle.
I still struggle with this, but now I come home from work and get some exercise. I started doing Taebo, and then started running outside and going to the gym. I LOVE it! Getting exercise is now how I relieve my stress after work, and after I exercise I feel good about myself (instead of feeling horrible about myself like I did after eating too much). I never would have guessed that I actually would enjoy working out this much!
Anyway, the moral of the story

is to decide what will make you feel better: eating junk or losing weight?
