Truthfully? External validation. I'm addicted to receiving reactions and replies. But also the community, of course, really nice and smart people here, people who actually try to and do understand me. I barely interact with others irl, so this is the most I've communicated with anyone in a long time. I don't expect to make any long term friends here, because I can't maintain friendships period, and well, the nature of this site, but I like pretending I have all these friends, and that makes getting out of bed feel a little less impossible.
