I have ulcerative colitis. I am really struggling to deal with anxiety with my condition. I also have a suspected fistula and looks like it is in 3 different places from rectum, vagina and bladder. Supposed to be having mri in Aug. My anxiety is all over the place. Currently taking mirtazapine. Have a phobia of general anaesthetic and surgery. Do you have anxiety due to an autoimmune condition? Any advice would be appreciated.
