@Hell...Hath...No...Fury.. Wow, I am really surprised and saddened to hear that. I am not in your country but was under the impression that Julia Newton was one of the premier ME/CFS experts in the UK from other threads. How could she not understand that you are bed and wheelchair bound and cannot do GET? That is disappointing to learn. Are you going to keep seeing her? I don't want you to end up injuring yourself trying to follow her treatment plan.
Her background is in geriatric syncope / orthostatic hypotension issues and she has an interest in OI and POTS. Judging from the papers she's written and a video presentation she gave (can't remember where I saw it), she doesn't have any real grasp of ME/CFS.
