Ulcerative colities, SRUS. Unbearable.

It's been almost 2 years since I was diagnosed with UC. Had got my colonoscopy done 4-5 times till now with ,had got sigmoidoscopy done. Also I've been suffering from vomitings, got my endoscopy done 3-4 times as well, it says I have grade c gastritis which got reduced to B. Also I've been taking treatment for depression since last year and half and am on anti depressants, sedatives like clonazapam as well. I've already been admitted thrice since last year and the latest being Couple of months back i.e in march. Since last week my abdominal pain has become unbearable with blood in stools resulting in weakness. There's lot of Mucosa in stools . Vomitings have become worse, with me losing 10-13 kgs without even excericse. last colonoscopy was not completed as there was an acute bend and as I denied anesthesia, doc thought it'd pain a lot to take it further so they stopped it and found that it's SRUS. Earlier 3-4 colonspy biopsy said I have active UC. I'm on mesacol, pain is unbearable.
