Update: had to fly to my mom's house because I was too weak to stay alone in my apartment. Found a great GI specialist who first tried putting me on antibiotics for a week to rule out infections. He also gave me an IV to counter the dehydration I was experiencing, and did another CBC. My red blood cell count was 10, where 13 is the lowest normal value. White blood cells were high, and I still had constant low grade fever, albumen was also very low, indicating malnutrition. At that point I weighed 138lbs, down from my normal weight of 162 (with low body fat even at 162 since I work out a lot).
Antibiotics didn't work so we did a colonoscopy a week later. Got another emergency IV and was immediately put on prednisone. They could tell it was ulcerative colitis immediately, and the pathology results from the biopsies they took confirmed this a few days later. The prednisone has worked to reduce the inflamation. I no longer have to go 20+ times a day, I'm no longer losing water through diarrhea, and everything that comes out actually looks like poop, albeit small fluffy/raggedy pieces, and still go about 4-5 times a day. No more blood showing up there either, no more abdominal pain, and no more fever. I am eating a ton now, trying to regain weight and rebuild strength.
At the lowest point I was probably close to death. I haven't weighed 138 since 9th grade (and I was probably a few inches shorter at that time too). I looked like an AIDS patient. I was so weak I had to be in bed all day, and getting up to go to the bathroom would give me a head rush and sometimes my vision would black out completely and I had to hold on to a chair or doorway until that would pass.
I'm so glad that the worst has passed now and that the rest is now to find the least toxic medication that will put me into remission. The one I'm now is not something you want to be taking long term due to the side effects. the worst effects so far are insomnia (I just take benadryl to counter that for now), and the profuse sweating it causes whenever I fall asleep. I have to lay out 2 extra sets of clothes by my bed every night because I wake up every few hours completely drenched in sweat.
