I have all but stopped pain meds, maybe that is it?
Or more likely is that although my rehab is going well, I am still unable to take on any 'real' work in the studio, and I think this it the reason for my malaise.
I am also relying on my walking stick a lot, as I am not confident walking any distance without it, and I am scared of being bumped in crowds.
I am sure things will get better soon.
