I do something kinda similar, I guess it counts as maladaptive frugality? Whenever I have something a little extra in my fridge, most often Italian prosciutto, I refrain from eating it, instead saving it for a "special occasion" even though it is, like, my favourite thing in the whole world. Eventually I have to throw the mouldy prosciutto away because I was too frugal to eat it. I'm practicing though, learning to ea…
One could try to reframe it that having it sit in the fridge going bad is a waste of fridge space/electricity/food/mental energy and unnecessary personal suffering.
