Stomach Pains

This morning I woke up and went to my 8am college algebra class. I brought a bottle of water and a granola bar with me for breakfast. My stomach has been feeling a little weird lately and I'm so tired. When class was finished , I walked back to my dorm. For some reason, I went to the cafeteria and totally pigged out. Hashbrowns, eggs, sausage, fruit, biscuits and gravy ugh my stomach hurts so bad. I feel like I'm going to throw up. I feel so disgusting...
