on july 4 in the afternoon it was hot and i walk around without a shirt on, my friends and i went to my house and as soon as i got there i took a shower and hop back in my friends car and i started sweating a lot. we went to the beach to watch fireworks but within 20 minutes i felt like i was going to faint and i felt so sick so my friend took me home. the next day i started having diarrhea until now. it was getting better i still have diarrhea but it came from being watery to just being mushy until three days ago. three days ago i hardly ate and that night my friends and i started drinking a lot, next morning i use the toilet and i had diarrhea it was mushy and it was light brown and it had like black dots. i also felt like i didnt want to eat all day. i only ate not even a piece of pizza when i woke up and that afternoon i ate just a little bit of rice and shrimp. i went about my day till night time i drank coffee then all of a sudden i felt sick i felt like i was goin to throw up, that night when i went to slept i was having night sweats and this morning i went to use the bath room and my stool was kind of dark and it had bubbles in it, kind of like mucus. i want to know what is wrong with me i am thinkin about going to the emergency room today and see whats going on..but before that i want your opinion.
