Heyy, welcome! I'm pretty new here too (a returning user who fell off the dieting bandwagon, hehe), but I can relate to your situation, as I am also a University student and have really struggled with stress-eating. There's nothing like donuts to make studying a little less painful... and in my case, I often have trouble sleeping because I'm all keyed up from hours of working hard, so I have a habit of eating a lot late at night to put me to sleep.
I'm glad you're here, good luck with everything and I'll see you on the message boards!
