You are not alone in going down a dark path thanks to the advice of family and friends.

FWIW I am using public LLMs with a friend's depressive thoughts and it is not doing what is claimed in the article, so I dunno.

Also I am in a relationship and my girlfriend and I agreed that we will not talk about our relationship much. We do not tell others if we fight, because they take sides and make things worse, typically. LLMs are definitely not alone in this, although in my experience LLMs did not really take sides.
