Therapy as currently practiced struggles to show any statistically meaningful results in reducing mental illness. People are right to have some questions, especially given that the therapist has a strong financial incentive to keep the patient coming back.
Okay, I don't know where you're getting this but you are
very wrong for what it's worth. CBT has a
long history of being extremely effective in reducing rates of GAD, SAD, MDD and a host of other mental health conditions, and especially in terms of alleviating those conditions even if they can't be totally eliminated. Particularly when combined with medication the success rates for CBT tend to be in the high 70-80% of people reporting significant improvement a year later in the various studies I've read on the matter.
Please don't post this harmful and wrong info out there and while I've never been a therapist I know quite a few who 1.) Make very little actually, when the difficulty with insurance and clients flaking comes into play 2.) Genuinely care about their patients and want to help them do the best by always staying up to date on best practices and building a healthy repertoire 3.) Many who actually take on a host of low-income clients to offer services to people who can't afford it, sometimes for as low as $10 a session or even less.
Yes, there are definitely shady mental health practitioners out there of course... But the vast majority of the people in the field are there because they have their own struggles with these issues and want to help others in the ways they may have helped themselves.
