This is a great thread. I don't interact one-on-one very much because I have to sleep so damn much with my illness, but I'm a fan of quite a few people on here. They really bring a bright spot to my days. Though I'm mostly reading and kind of on the sidelines here, there's a few users I have to mention:
@-Persephone- has such a way with words; she expresses complex feelings so expertly that I often feel like my own emotions are being expressed at the same time.
@GenesAndEnvironment has a remarkable talent for popping in with a joke that makes me crack a smile even when my brain is stubbornly determined to be in a bad mood.
@whywere 's genuine good will and kindness comes through in each comment he writes, even simple ones, it feels like sitting down with an old friend for coffee.
@Midgardsorm 's posts are both empathetic and informational, something that I really admire, as it's a combination that I know helps a lot of people.
