I've heard the same thing from mental health counselors and therapists. In wealthier areas many will just stop accepting insurance entirely and make people pay out of pocket to avoid all the insurance paperwork and requirements (some insurers require specific diagnosis to continue paying for services). If an insurer decides to not pay you? good luck. Now you need to throw hours of unpaid labor at them to get money you're owed.

Unsurprisingly, this means many normal people can't afford a therapist and they're getting harder to find.
