The trouble is that talk therapy is already too expensive for most patients, and unless you plan to have people tripping with a therapist who is a complete stranger (not advised!) you're going to need to charge for some preliminary sessions. If a typical therapist charges $100 per hour -- and that's optimistic, in fact I've never paid less than $125 -- then the cost of treatment quickly runs into four figures.

That's already more expensive than a year on SSRIs, as crazy as that might sound. Human interaction is shockingly expensive.
