Sometimes I Overthink Too Much About Nothing

I mean, I was just walking to the grocery store and all of a sudden I start thinking like 'What if this bag has been touched by a thousand other hands? What if there are microplastics on everything... What if they're all crawling into my pores right now as we speak? And then I got paranoid about using cash because what if it's carrying germs from the last person who held it... It’s like, sometimes I just want to scream and throw away all my possessions, but instead, I end up buying an extra large pack of hand sanitizer just in case. Am I overthinking everything too much? Or is everyone else out there just as paranoid as me and they’re just better at hiding it?
