Hi fedupn45, welcome to the forum.
Unfortunately computer based assessments are just that. The doctor enters information or misinformation into the computer, the computer makes suggestions, and in some cases the doctor simply accepts what the computer says!
I think you should phone the DWP and ask for a copy of your ESA85 medical report and a GL24 appeal form.
The ESA appeal guide which you can find
here will guide you through the process.
Please don't feel humiliated or a fraud; they appear to be stopping everybody's benefits with their sub-standard assessments and nobody with any understanding of them takes them seriously.
Good luck
Derek
