I gave up looking for meaning in things like failed therapy. I find life largely arbitrary. Suffering and good fortune are not distributed evenly. People want tidy narratives. Good luck with that. I think getting scammed by therapy says more about the institution, the organization of society, and established hierarchies than it does about the victim.

Also, as someone said, most healthcare is a racket. I've been to 50-60 different practitioners past several years in pursuit of help with chronic illness. Most took my money and delivered little or nothing in return (though some gave it a good shot). I think most people selling cures or transformations are basically snake oil peddlers, or are vastly overselling what they do. Therapists especially.
