Is this a chicken and egg situation?
You are concentrating on the need to eat, and of course it is essential that you do that. The other side of it is why can’t you eat. I feel it is also essential to address that issue.
You are experiencing as many others are the lack of help from professional services. This is a serious problem, and realistically won’t be solved any time soon.
You can look for alternative kinds of help. This is your only option.
I see you have family, is that an area you could explore to identify someone who could provide a listening ear? People who may have been too busy in the past may be able to be available to you now.
A PP mentioned Mind. They are a brilliant organisation and I would second that recommendation and definitely pick up the phone and ask for help.
Self help is also something you could concentrate on. Not just on the need to eat and wash.
Make a list of the things you liked to do and gave you pleasure in your past life pre illness. Access one of those things a couple of times a day even if you’re not feeling it. Regain familiarity with wellness.
Crosswords, drawing, reading, music, favourite programmes, crafting etc.
It will feel alien at first as you do not feel you. But practice is key.
You are not alone, people do care, reach out and ask for help.
I wish you strength to do that.
