OP, my body would probably rebel against me too if I were eating the shit you're eating. It sounds miserable, man.
Look, I'm going to assume that along with the foods you listed, you basically have a similar cafeteria to the one I had when I was an undergrad. I'll also assume you have no money for food otherwise--if you do, invest in a protein powder. Here are some possible changes:
-Breakfast: screw hash browns and french toast, and definitely screw the orange juice. Drink milk, stick with eggs and the breakfast meats if that's the best you can do. If vegetables are available, have at em. If not, then whatever you'll live. Piece of fruit or whatever is fine.
-Lunch: Prioritize the salad, fuck the dressing. Is peanut butter available? If so, and I'm serious, take a cup full of eggs and mix in a few TBSP of PB. Again, drink water or milk. Get some meat in there however you can.
-Dinner: stick with a Green Face approach. Get whatever vegetable is available unless it's deep fried, and get a shitload of whatever meat is available.
A lot of this is contingent on when you workout. If it's right before lunch, then you could probably leave the buns on the cheeseburger and be fine.
