Crying won't help but sometimes...

I know crying doesn't help but sometimes you just have to. I know asking won't give me answers, but why me?
Eating hurts. It doesn't matter if it is just applesauce or yogurt. My stomach literally hurts. It isn't just nausea or gas. It hurts. My whole abdomen gets rock hard. Sometimes I get gas. Sometimes I vomit. But not until after the pain. I've tried eating slower but most of the time I eat so little that I don't know that it makes any difference.
I'm having another one of those weekends stuck at home. I honestly feel as if leaving my apartment would be dangerous. I'm dealing with the stomach pain, pain in the rest of my body, the headache, the dizzy spells and the overall feeling of just being sick.
I hate this. Why me? I know it doesn't do any good to ask but I can't help it.
