It's okay. I can go to bed at three no problem.
I don't really care if internet people just disappear. After all, I do that on the internet all the time too. It usually just means I grow out of something.
As for it affecting me somehow, yeah, sure I think it sucks that you're not happy right now, but I have compassion for most people. You need to see a licensed mental health professional to talk through your problems, as I'm sure you know already. I mean, of my two best friends, one has seen a therapist and the other has kids who are in therapy. It helps, so that's what I recommend.
