Maybe stop doing that then. I can get a weeks worth of food for that kind of money and it tastes good.

I am fortunate we have enough mental energy to go to stores to buy ingredients to cook our own meals most days.

Its similar, to what is referred to as “adhd-tax” I am still in this picture more then i would like.

Doesn’t really matter what your mental energy is if you don’t have the money to have any other choice. Few years ago I was comfortably living on under £100 a month after paying rent for a bedroom, then putting the last £75 or so of my income into savings.
Also half of Americans live in “food deserts” with limited or no options for fresh, healthy food/groceries. Often their only sources of sustenance are the dollar store and fast food.
Maybe, but I hear the same things here and I am not aware of food deserts being a term in the UK.
