Q: My life is falling apart on all fronts and I'm struggling with physical and mental health issues; what should I do? A: Read this book. Only on HN...
Bashing people trying to help is usually a reddit thing, but here we are. This website is a text based medium. Literally the only thing that can conveyed here is information. Books, as you are aware, can contain even more information and advice than this website. If the person was looking for something other than information and advice, they would be looking elsewhere.
Verbal clues and facial expressions are also pieces of information, so the fact that HN is a text-based medium does not set it apart from other communication mediums only because it conveys information.
People going to HN to ask for help probably do this because they are familiar with this community, not necessarily because it is text-based and probably haven't rationalized this aspect that much.
Anyway, good luck to OP. I don't have any insight on this matter.
