You need to prioritise that bottom layer of Maslow- eating, drinking, eliminating and sleeping.
The rest will follow later. Maybe try washing hands and face before having something to eat. Clean teeth and change into clean PJ's after getting up. Don't worry about the washing for now.
Make a list and pin it up-
Get up.
Go to the toilet.
Wash face and hands
Clean Teeth
Eat
Drink.
Meds either before or after eating, depending upon what the instructions on the packet say.
If you can change your clothing but don't worry about washing clothing for now.
Make meals light and with minimum effort-heating soup, toast,, fruit, sandwiches. If you have spare motivation, make an extra sandwich to eat when your energy is low.
If you have any spare energy/volition then try to go outside for ten minutes (For Vitamin D and good effects upon diurnal rhythms).
Open your curtains and blinds and try to sit near the light from windows.
Set alarm clocks to remind you when to drink and eat- every couple of hours for fluids and a full half a pint glass at least.
Set a bed time. Change into night clothes (important for diurnal rhythms again, telling you the difference between night/day) then reverse the morning routine above.
