Please help me asap!!! Earlier today my stomach was feeling a bit off, but I paid no mind to it. Then, at swim practice, I was very overworked, and it got worse. I thought it was just hunger, so I ate a quarter of sub. And then it got even worse! That was an hour ago and it's not better. I took two Tums and have been relaxing. I had a regular bm and am passing gas. Not getting better. It feels horrible - a mixture of cramps from being overworked, cramps from gas, being very full (although I am not), and n. I can feel the n in my throat and stomach. I am feeling very panicky and I'm doing my calming techniques: deep breathing, siting back and relaxing, watching a non-triggering tv show. Please help me because I'm terrified that I'll v!!!
