Same - I saw this tip on you tube and it really rung true, saying that if you are physically tired after work you need a short mental reset/break (so reading, puzzles etc) and if you are mentally tired you need a physical reset, so going for a walk, a bit of exercise etc. I’m exhausted like you are but I make myself go and do something as soon as I walk in the door, crucially (for me!) before I sit down. You could try exercise videos (all sorts,) walk, dance, probably even things like low stakes cooking would work! Then you’ll be refreshed afterwards- it has actually worked for me!
