Digit is someone I was friends with on the internet a few years ago and worried about all the time since then. She had cancer when we were friends and got better with surgery, but then she kept talking about suicide a lot. She had lost a boyfriend to suicide previously. She ended up deleting her accounts to make me think she might be dead, then eventually she let me have some sign of life again in the form of a Spotify playlist, but I'm still scared all the time.
