>>33351349 (OP)If you hang around in a place like discord for long enough (presumably in a discord you like, shouldn't be hard if you are the sort of person that posts that anime picture and presumably self-diagnoses as mentally ill) you can make at least acquaintances. I haven't bothered with it in years and don't like talking into a mic when I do, so my experience with it is limited.
These online acquaintances can be a replacement for friends for some, but they may or may not satisfy your psychological wants, needs, and other social interests. For many, being alone is better long-term.
Its like a more engaging version of being a prison pen-pal. Sure, anyone can do it, but milage varies.
