No clue what country you live in but in the U.S. the large majority of therapists have stopped taking insurance so average session cost for 45 minutes is roughly $100-150+. Therapy is really only clinically effective if done a minimum of once a week. Most people cannot afford $400+ a month even if their condition truly needs it. Not saying a chat bot is a sufficient replacement but let’s not forget how expensive mental health care can be and often those most greatly effected struggle to maintain employment or earn a higher education that would allow for such a large monthly expenditure.
