So very sorry to hear of cancer being terminal. Very important for cancer persons and diabetics to have meals with protein.
Eggs, milk,steak, chicken, corned beef.
However, as you say that often not wanting to cook is there anyway you could have a meal a day delivered?
Being terminal, you do have to consider the quality of life you have to enjoy.
When do you expect to have something in the way of medication/confirmation?
I would (if it was me) ask to have medication asap sorted...with levels in20's you need medication rather than trying to stop certain foods etc..your quality of life is still very important..
My cancer was breast amputation... And I know a little but my diagnosis wasn't terminal. However, it still impacts hugely on thinking about quality of life. I hope you can get medication as a priority as to me endless trips to loo and constant drinking is impacting on your life and should be relieved quickly..
Thinking of you..xx
