it's literally me

Same, except it's my bathroom floor with the shower running with airplane bottles I stole from the liquor store instead of an e cigarette and I think of all the things I happened to instead of "happening to" me like some cute twink with an external locus of control.

Imagine you're a social outcast and suffer from anxiety and other mental issues

You spend a lot of your time online. You find a community who finally welcomes you and accepts you. They tell you that the reason you don't fit in anywhere and have anxiety and depression is because you're a vampire.

Everything finally starts making sense to you. It's not your fault you're weird and aren't accepted by others. It's because you're a bloodsucker. The grooming gets deeper. You post on /h/vampire. Your relationship with this cult strengthens. You feel accepted and loved, something no one has ever given you. You contemplate turning into a bat and start watching Bram Stoker's Dracula like the vampire you really are. You still aren't accepted by others, your label as an outcast worsens, but it's okay. They're intolerant of who you really are. They're mind controlled by the !edgelords. They're the problem, it's never been you.

It's not a community. It's a cult. It's predatory. You start grooming others too. This is the only normal you know. Society is to blame.

If you aren't writing revenge plots in your diary while you're doing it, then you're a fricking poser.
