I have had great results with both TKRs but sometimes felt "down". It helped when I read in Bonesmart that this is normal and temporary. When I couldn't sleep because of the pain, I realised it was better than tossing and turning. I would get up and deliberately watch old comedies. I also admit, I had the odd Malt whisky as well.
Pretty soon it will be behind you and then enjoy that new knee.
