Omg sick blah

Its 6:43 a.m and I'm up sick with sorry tmi but diarrhea ,one of the worst stomach aches you can name. Only time I can relax is when the central air is on. This is my 2 time being up again ,if I leave the central air on while I sleep I'm fine ,if I turn it off and I get hot . my stomach instantly starts hurting I get the feeling I have to throw up but it just ends up coming out the other hole. This never happened to me before while was sick 21 years of being sick and I never had this happen before.
