have i forgotten how to food

i think from today i will be trying to a avoid supermarkets for as long a i can now. shopping has become a pain in the ass. on a normal day i can find shopping a challenge partly because of my social anxiety but mostly because most food is not packaged for one. so to avoid food waste i have become rely on food with a long shelf. but now this is the food that is selling out. but over the last week i have built up a bit of a stock up so i think a can stay away from to supermarket for now.
