Are you suggesting that when friends are giving armchair mental health advice that they actually went out and thoroughly researched your situation, somehow without you ever realizing it, as well as did a review of recent medical literature on possible solutions?
That would be quite amazing, but some people have amazing friends. Unfortunately, others might not be so lucky.
I think you have the wrong perspective. Reddit is garbage and it took itself out of your life, which is about all you could ask garbage to do.
