I'm glad you have managed to hold on so far - please keep going. And it's great that you have such a supportive team there.
The pain does make things so much harder, and I can see what you mean about the problem with grounding yourself bringing your attention back to the pain. A couple of ideas, in case either helps: I have a 'safe place' in my mind to go back to if things get too bad, and I made it somewhere I'm comfortable, warm and safe. You probably already have one, too, perhaps aim for there? Also, could the physio be done with you sitting but leaning right forward? I'm thinking of something like sitting on a chair the wrong way round, and the chair having a back that could tilt so you would be in a leaning forward position where you could have relaxed muscles. It wouldn't be as effective as lying down but might be easier to tolerate, perhaps?
We're here for you.
