I seem to have a few people in my circle who often post things like "really struggling with mental health today" or "can this day get any worse?".
I like to think I'm a supportive, kind person and if anyone were to say that to me face to face I'd be all ears and want to help if I could. On line, I'm afraid it makes me roll my eyes.
If it was a close friend I'd call them to find out what's going on (but my close friends wouldn't do it). These are people I know to have a chat with if I bump into them, but not close friends.
