Boy, it does sound like you have a stressful life! I "feel your pain!" It is so hard to work full time AND go to school. And I'm gonna guess you have a family, too! No wonder! If you aren't getting support from home, log on here and we'll be your support system. We want you to succeed.
Do you find yourself eating just to calm yourself down? I know when I was working way too much I found myself eating just to slow myself down. I also found that I never felt like I "ate" (table, plate, chewing... that sort of "eating") although I was filling myself by speed grazing. Then when I did get to "eat" a meal I would over indulge.
It helped when I stopped grazing and paid attention to how much I really was eating. And just knowing that I needed some "calming" did a lot to stop that bad habit.
I also found that I was rewarding myself with food beause I did feel so overworked and underappreciated. Again, just knowing that I wanted to reward my expanding butt with more chocolate made a difference in curbing that habit.
Thanks for letting me have a little "therapy session" here.

No, really, good luck. Let us know how you are doing!
