Going to try to catalogue how I feel for a few weeks. This morning I'm exhausted. Feel really weak and shakey and struggling for breath. I'm having trouble even walking up stairs. I was supposed to be in the office but I'm working from home because I didn't feel safe to drive this morning. Not too dizzy though and no visual disturbance. I'm in a lot of pain because I had physio on my shoulder yesterday but feel achey everywhere else as well.
