ESA DILEMA WRAG causing suffering

My wife in March, filled in the relevant forms moving from IB to ESA , shes had a ATOS medical and the decision is that she's been placed in the WRAG group CB. She reluctantly, was terminated from“ any work “ in the NHS. 6 years ago. She is 50, and she's been previously diagnosed with chronic asthma and Lipedema ( not lympoedema). She been told theres on numerous occasions, theres NO cure for the lipedema and management is very poor. Because of asthma, cant have stronger pain relief and she's in pain mostly severe, even at rest. Been told by specialist, that Diet and exercise will have not have an affect on the condition. In fact symptoms have got worse over the years. After asking for an explanation from DWP, which stated “could be available for work in 18 months, and can walk 100 metres”, although both her legs are hard and 2 to 3 normal size.and she is in constant pain. AND I cant remember the last time she walked 30 yards not in pain. ( it beggars belief where this 18 months and walk 100 metres as come from) – The medical services report states that “her legs are grossly over sized , found walking 15 meters to be in pain and breathless and this was found to be consistent, and the evidence suggests she will have some problems with all lower limb activity- significant disability is likely. She has appealed with support of her GP, and forwarded photos and GP letter,in the meantime she now has to attend work focused interviews, the next, is this monday and she has had to have, enrolled for an I T class , and filled in a .CV.
She's been told, by her JC +personal advisor, she would not have to look for work until 18 months. And the WFIs are to get her ready for this. She has formally requested a deferment WFIs , until appeal, or has been looked at again, but been refused.
Yesterday she's been diagnosed with IBS of which requires further tests to see if its not more sinister. The GP is saying to avoid stress, rest -laying down, as much as possible and elevate her legs, to try and ease the pain, Her GP states she is very anxious and states categorically that she has deteriorated since the first WFI and I agree. The personal advisor at the first WFI , stated she could see how much distress she was in, after travelling etc and sympathised with situation by making the WFIs 6 weeks apart.
I do admit , she get very anxious and worries too much, which is, I think is leading to depression. Her JC+ personal advisor has recommended she applies for PIP and a disabled bus pass. She feels she would be sanctioned if does not attend the WFI , but her GP is indicating, not to comply , because her long term health is more important.which as created this dilemma.
Does she, what seems like going against her GP (medical advise)and take active part in attending the WFIs. Or get sanctioned, and do has her GP keeps telling her. Eg . Avoid stress, rest , elevate legs etc. She, I and her GP get feeling that these WFIs are just playing lip service to the system. Could she voluntarily give up the WRAG part (I dont know how much) of the ESA payment, at least until the appeal is heard , and it sounds like she would have to reapply in 12 months any way, because of CB award. The recent diagnosis of IBS and the lipedema now looks like its starting to affect her arms. ALL since this the first WFI. clearly this is exacerbating her illness and even adding to it. Would would be the best direction to address, her case with the DWP. ?
