All of these being experienced!
In terms of the appetite I make my own soup as find that very comforting and easy to eat. I find making it cathartic as well and enjoyable. Nice smell in the house as well.
I have a bath with soothing bath oil or bubble bath every night, usually quite early in the evening and go to bed early even if I can’t sleep.
I wake up very early and if I haven’t got to get up for work make myself tea or a coffee and take it back to bed and relax for half an hour. This really worked when my Father passed away many years ago, Mum and I used to lie and chat together in her bed until getting up time. It seems to be helping now I have lost Mum.
Would really welcome any tips from others.
