3 weeks in

So as it's a nice day and I've sat around for the last 3 cold ones I thought I would potter. I've washed the car (that I cant drive for a month) then walked the dog for prob a mile. Now I feel absolutely bushed. It's too easy to feel good about yourself and do things only to realise you've done too much. It's so frustrating right now I'm thinking will I ever get back to work.
