Some of the things you have stated here @creative_writer are not actually the case.
Yes everyone is trying for recovery, but not everyone feels that everyday.
There are lots of posts of people just sharing their story and sometimes it's not a "happy" story that day or that post.
There are guidelines but they don't preclude talikng about pain or how you cope (there are some exclusions to that).
Most people on here are not "cured", if any. Many people have chronic mental health conditions.
There are social threads and places where people post memes and uplifting things they've found, but other threads are people's real lived experience.
