Appeal strategy for support group

Andywheels56

I have been placed in the wrag group for cb based ESA. I did not score any points at all but I qualified through regulation 29 on the form they sent me. They have decided that I suffer from a specific disease or bodily or mental disablement and that there would be a substantial risk to my mental or physical health if I was found not to have limited capability for work.  I requested an MR and sent a bit of general evidence but I have just got the reply back that they have not changed their minds and I remain in the wrag group. In the MR letter they have written that it is accepted that I am not fit for work at present, but the issue is wether I can do work related activity. How do I argue that reg 35 should also apply. I have looked at the support group descriptors and although I can manage them I cannot do them all the time without causing me undue distress and anxiety. 

Any thoughts on an appeal strategy would be greatly appreciated, Thanks.
