The way I am dealing with it is to try to keep to the same routines. Get up at same time, eat at same time, bed at same time.
I also have made a list of little jobs that need doing - nothing major. I work a lot on the garden and Spring is a busy time like planting seeds and nurturing them. Also, things like tidying the garage, sorting stuff, garage door needs painting, metal gates could do with a coat. Then there's housework to do. I like cooking so I cook up meals that can be frozen like cottage pie, chilli etc. I also am doing a 1000 piece jigsaw puzzle, learning new songs to play on guitar.
Tomorrow (Monday) is clothes washing, clean sheets on bed and hoovering, a little nap after lunch, then do some cooking for my tea time.
