Honestly this sounds like an incredibly small amount of work when considering the work involved in traditional therapy and/or psychiatric treatment, which plays out on a timescale of years if not an entire lifetime for some, and collectively requires a “medical team” numerous times.
And when the outcomes involve radical (lasting) improvement to everyday experience for individuals with treatment-resistant depression, I strongly question the urge to trivialize this with scare quotes about “good” experiences and their apparent cost.

The good news is that there’s been quite a bit of progress, and growing interest in medical circles due to the positive outcomes. I’d strongly recommend looking at the latest studies/results; it sounds like you may be operating on some very dated information.
