I'm pretty much at 6 months into my recovery now and most of the tiredness from pneumonia has lifted. I can over exert, but we are talking 60 minutes plus of exercise to make me feel it the following day.
As I got back to full time work, I decided to slightly reduce the amount of walking distance I was doing to again find my baseline. I've done 2 weeks of physio now also, and each session is 60 minutes. I managed the second one rather well, although I do still get aches and pains.
I'm managing 20 minute walks almost every day, plus pottering around the house, and doing things, such as bring the shopping up when delivered.
I can stand in the shower now!
My leg weakness is reducing too. My neck pain was diagnosed as cervical spondylitis, and the physio thinks its related to my deconditioned state. I was on bed rest for 3 months pretty much, so lost a lot of muscle mass. To reverse that, could take 6 months, and i've been exercising for around 2 months.
Thankfully, my neck seems to be improving with the treatment program. However I need a fair amount of painkillers on some days, just depends!
The aim is to build up to 30 minute walks and hopefully have the strength in 1-2 months to resume jogging, when my legs are strong enough.
Sleep is improving, and the use of a worry diary helps, but I only do one when needed. Most days I have no worries now, as day to day, what is there to worry about that needs my attention that night!
So all going in the right direction!
