So recently I started back at college full-time after taking a 3 year hiatus to work/travel. I really don't think I prepared myself for how much work it would be to go back to a full courseload.. and I have found these past 2 first weeks incredibly stressful and tiring.
I find that by the time I get home from class I'm so stressed with all the reading I have to do and homework thats due the next day that I have been mindlessly eating really unhealthy stuff. I need to be doing the opposite because my intention is to lose more weight and be healthier. I feel so comforted by food when I get home from school though that it's becoming a major issue for me. How do I come home and eat without seeing it as some big break and comfort from the day? I know even healthy food can taste good and be comforting, but as someone who has trouble with food and binge eating, is it a wise thing to seek food as a comfort at any time?

I'd say it's probably a better idea to figure that out and find something non-food to make into a 'stress habit' after class than play the "binge on celery" game, because celery isn't the same as a bag of chocolate no matter how you put it.
Best of luck with your classes! Getting into a routine that works for you should help with some stress too.
