During the pandemic I gradually lost contact with my friends. The last person I talked to was a girl I really liked. I think I had a crush on her, but that doesn't matter anymore. She moved to another city, so I decided to remove her number from my phone, to not to talk to her again. Then I started to remove almost every phone number of those I considered friends at some point of my life. In order to cope with my loneliness, I've started to consider that all of them died. Is it healthy?
