Ulcerative Colitis questions: Confused and frustrated

I have been navigating a UC diagnosis for about the last 6 months. Previously the stool bleeding was diagnosed as hemmeroidal, but things continued to progress until a colonoscopy revealed serious inflammation in the colon. After a grade 3 diagnosis, the doctors pushed for humira. I tried a very strict, anti-inflammatory diet first, and it helped a lot. Still a little blood in the stool tho. So tried mesalamine both oral and the suppository. I thought things were improving using b, as the color I saw in the stool was purple rather than red, but doctors said it was still blood and pushed again for humira. I took their advice and am now approaching the 7th injection. I have more bleeding now than ever and I have abdominal pain and urgency. I am definitely in the middle of one of my worst flareups. Anyone out there have a similar story and advice? I'm feeling confused and frustrated.
