Soop I hope you are not overdoing things? Even "-so-slightly (as if I believed that) knackered" is not good.
I find hospitals incredibly draining and I am not even the patient! It is impossible to relax, and waiting to be called makes me realise what patient dogs waiting in the car or outside the newsagents for their owners to return, must go through. You know how they prick up their ears, then droop again when it's not "Mum" or "Dad"
We have a clinic appointment in London on Tuesday and despite Mobility Assistance at Euston and taxis everywhere else, I come home drained, so goodness knows what DH feels. Anyway I have come up with a cunning plan and have booked a car and driver for the whole trip. Doing it by train and taxis costs between £65-70 depending on traffic between Euston and the hospital and because we go off-peak, cannot travel back between 4 and 7 so often have to kill time in London which means more expense on a meal. And it is all so BUSY. I have been quoted a similar amount plus some of the waiting time (first hour is free) to travel door to door in an " executive" car(that is to say comfy ) with a highly recommended driver, not yer average mini-cab driver, so while it is expensive, I really hope worth it as I fear we could be getting to the point where DH is not necessarily well enough to go to these very necessary appointments.
