Oh dear god.

OP go see a doctor first thing Monday. In the meantime, fix a proper meal with a fresh veggie salad, medium-rare steak and a few roasted red potatoes. It won't hurt to go get a few bottles of mineral water so your body can replenish your vital nutrients (you need minerals to process vitamins) and maybe take a good multi vitamin tab with the proper meal if you have some on hand. Eggs are a good choice for breakfast. Eat some yogurt too to replenish intestinal flora.

SEE A DOCTOR MONDAY.
