It does not matter that people that create startups are logical, etc. This doesn't mean science-based medical health won't help. From what I have observed, mental health care includes things like medicines to help with inbalances as well as offering things like groups, help with stress management and coping skills for a person's situation. It isn't about changing your world view, it is about helping you not be miserable.
All of which are individualized to the person's needs as possible. 'Do what works and discard the rest'.
As far as 'extending beyond the boundary of humanity today' ... that's a bit diffficult to even think about if I'm having trouble convincing myself that I do, indeed, need to shower and cook food and go to work today. Research? Have to have concentration for that. The therapist isn't there to research everything, just to get you to the point that you can research yourself and help you if needed.
