Hello,
I don’t know you and you don’t know me but what is clear is that I am me therefore you must be you. I used to have such a hard time with that. That being that other people exist and its not just me and everyone here is a figment of my imagination.
I used to stare at their heads and wonder what would happen if I were to smash it in with a hammer. Just to see if there is something there and that I’m not alone. I used to get these urges all the time at university when I started to notice things weren’t quite right.
