Asleep - hang on in there, you're amongst friends. I've not had PND, but have had bad depression for a few years now.
Am currently doing okay, so I'm able to give you lots of empathy from here! Speaking very personally, my life-saver is painting - I took up my water colours again (after a break of 20+ years since A level Art), I painted when I was in the Priory, I joined a life drawing class, and now I've applied to do an Access Course in Art & Design at Farnham Art College prior to doing a Fine Arts Degree!! I never would have predicted any of this...
It is great that you can read, and that you want to paint too. Enjoy them as much as you can but don't beat yourself if there are days when you don't feel up to it.
