I get the anxiety, but I don’t really think people‘s minds would go straight there unless you really opened up about your mental health and having a literal hoarding problem. People say stuff like “[item] hoard” or “I have a ridiculous amount of [item]” without having/needing a real hoarding diagnosis, so those kinds of phrases on their own wouldn’t necessarily make them think of legit hoarding
I hope you don’t feel too bad about people not using for your magazines. People can often m be self-conscious about taking/accepting something even if it’s offered. Or they aren’t sure if it would fit the aesthetic they hope to have in their project, and are afraid that it would be awkward if they asked for your magazines and didn’t use them after all.
