Why is it you think this story reflects how the actual world is like? This is the experience the CHARACTER is living, albeit in this deformed surrealistic view of her world, and nowhere does the game state this is what every therapist is like, nor does it state that medication is inherently bad. You seem to think that this kind of media should always portray the "good parts" of everything, why though? There HAVE been shitty therapists prescribing shitty pills to people who didn't need them thus worsening the situation, this is the case here, that's it.
