as well, and have a similar problem. I can't just shop all day. I am in PA where last night we went into enforced lockdown. As with other announcements, it was followed by a run on stores. On my lunch I went to Target and a grocery store. Stores were actually in worse shape than last Friday.
I have a theory that going into a store and looking down the paper (or any) aisle and seeing empty shelves from the front of the store to the back creates anxiety and people think "I won't be able to get toilet paper when I need it, I better start stockpiling." I think people will not stop hoarding it until they can walk into a store and see shelves of toilet paper. Or whatever. This same store had no poultry and no red meat with the exception of some corned beefs (expensive) and pork (there's always a little pork left). Canned goods were sparse, I didn't look at bread, but last weekend bread was hard to come by unless you wanted whole wheat English muffins. Beans either canned or dry, forget about it.
It's scary to not be able to walk into a grocery store and put your hands on what you want or need, and I believe that's what is causing this behavior. I didn't start hoarding, I went to buy TP when I was getting close to needing it. I couldn't get it. THEN I started making sure I had more toilet paper than I would generally stock. It's still not obtainable, so I'm thinking I should have even more.
From an evolutionary standpoint, none of our genes would still be on this planet if we didn't have the an embedded urge to stockpile when we sense a shortage. And yes, I know toilet paper isn't technically food, but in our society you aren't going to get very far if eschewing toilet paper, so it's probably linked pretty close to survival, or at least security, in our heads.
