It absolutely drives me up the wall just how bad most of my friends are at being responsive. I have to deal with people not replying for days or even weeks (often while reading all my messages and making it even worse) and I've gone through countless times where I finally find someone I can reach out to and talk to only for them to start going silent for a week or more. I have no idea how to make reliable friends like other people seem to have and it feels hopeless and futile.
