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 eat it. I don't know why it's so hard, I mean it's delicious! Should be easy!

Exactly the key of mindset that drives me to play through entire RPGs without ever popping a single item. It is essential that I collect 99 potions, and never consume even 1.
