Ask HN: Talking about only positive things

Seems that people cut you out of conversations and stop responding to you when things are not going well in your life. This even when comes down to trivial chat messages. This seems to create a vicious loop, how can a victim of this wormhole and bystanders can step in and assist. This is not related to severe drug abuse or psychotic episodes. Seems that world is a harsh mistress to me and others and I wonder how can I help and what other think about it.
