UC Migration Confused

Hi, I made the mistake of filling in my UC claim in the midst of a block of migraine without checking on here first and think I've made a mistake. I've been on WTC for years with the disability element. I'm self employed and made a small profit this year on tiny takings. I was treated successfully for cancer at the end of November 2023, have chronic migraine (15-25 attacks a month), anxiety and depression, Coeliac Disease, IBS/reflux and a nice bundle of other conditions. The migraine and depression impact my daily life considerably but I have been working 31-32 hours a week. When I filled in the claim form I ticked the limited capacity for work box because I'm only able to manage my condition by working at home and can work around it there. I thought there would be another place to explain why but there wasn't. I have explained I'm working full time and self employed.

DWP have now asked for a Fit Note so they can start the work capability assessment. I have filled in two journal entries asking when they want this dated from and until because the last time I had one was 14 years ago!

My dilemma is that I need my current income level to be protected and need to be continuing to work full time for that, but that I'm also stressed to high heaven and exhausted. I don't know how to proceed. What are the ramifications of taking the limited capacity for work route in terms of income and interactions with DWP, please? Also is there a way of contacting them given they seem not to be responding to my questions?

Many thanks.
