Hi Cookie
Unlike the medical assessment, there isn't a predictable set of questions you will be asked at an appeal tribunal. Besides being questioned about your day-to-day life,it very much depends on your condition and circumstances.
I would strongly recommend that you contact, and preferably visit your doctor to obtain supporting evidence of your condition.
You can find detailed information about how to appeal in the ESA appeal guide in the members' area.
Best of luck
Derek
