I had similar (although probably less severe) after chemo. I am a lone mum with a ds to feed.
I wanted to switch to eating 30 fruit & veg a week to optimise my immune system as well.
I prepped all meals sitting at the kitchen table.
I explained the issue to our local butcher who delivered:
- home made sausages,
- home made minted lamb burgers,
- chicken breasts in a marinade
- Chinese spare ribs
- herby meat balls
- beef & mushroom pie
- ham
to my door weekly
I had Tesco home delivery for fruit & veg and everything else.
Meals were very simple but nutritious - sausages, French beans, wholemeal bread & butter, or lamb kebabs, wholemeal couscous and sweetcorn. Nothing took more than 5 minutes effort. Fruit, nuts, dark chocolate and Greek yoghurt for dessert & snacks.
If you can't afford good quality butcher's meat every day, do every other day and buy Cornish pasties or breaded cod for in between days.
£50 will be impossibly tight though. Can you talk to MacMillan and check if there are grants available to help? Good food really is essential to optimise your recovery.
If you live rurally, talk to your parish clerk. Parish councils have emergency funds to help in certain circumstances, and they may be able to help deliver stuff too.
Don't be afraid to ask for help.
