I'm not sure if I have any type of IBS but I hope someone can help me. On saturday, I went to the movies and drank maybe 5 sips of iced coffee on an empty stomach. I regretted that decision almost halfway through the movie when my stomach started acting up and felt like it was churning. After the movies, I was light headed and couldn't manage to walk far amounts and I felt like I had diarrhea so I would squat every time I got the chance before I got home. When I did get home, my fiancé was with me and he helped me of course and I went to the bathroom because I thought I had to empty myself but nothing came out so I went to my living room to lay down. When I laid down, my body felt the chills and I was the only one who was feeling cold in a 70 something degrees household in FL. I started to cry out of no where because of how I was feeling. I was exhausted and my stomach still acted up. The next day,I was no longer having the chills but I was dizzy whenever I got up from laying down and my stomach felt a bit worse than the previous day. I felt like I would pass out and I couldn't walk far. On monday, which is yesterday, I was still dizzy but not as serverely. I tried to function myself to go to school but I couldn't. I had the feeling that I was going to have diarrhea but whenever I went to the bathroom, nothing would come out. Today, tuesday, I'm home and I feel the same as yesterday. I have diarrhea thay won't come out and I feel like that is what's causing my stomach this aggravating feeling. I lost a lot of weight and I'm not 93 pounds, but I am 5'3 and I'm 17. I hope someone can help me out with anything because I honestly don't know what to do.
