I’m scared.

I was diagnosed with Ulcerative Proctitis in 2022. Yesterday I had a colonoscopy and I was told that they saw mild inflammation in my left colon ( so it spread). I honestly feel overwhelmed. But I do feel like my eating habits may have something to do with it (correct me if I’m wrong). I know it’s certain I shouldn’t be eating (greasy, spicy foods, dairy) but when I asked my doctor he says “you have to see what works best for you”. I get it but I want more information. What are some of y’all go to meals? I need some ideas!
