Hello legna
My personal experience is that the world is full of self-apointed experts. Not just in the field of recovery and mental health. Chasing them all down would take far longer than my entire lifetime... and what would I acomplish? I would just become a self-apointed expert and taking down self-apointed experts.
What I have learned is that the people who most impressed me during my recovery were not the experts. It was the quiet, dependable and gentle people who went about their life helping others without making any spectacle about it. Those are the people I try to emulate. I find that people that lead by example, instead of by proclamation, seem to last year after year. The experts tend to vanish rather quickly, without any help from me.
