My point is that people have to figure out what helps themselves. All of the terrible advice amounts to knowing there are people who have learned to manage themselves and therefore most people can learn to manage themselves.
I've been wondering lately if there isn't a model of care that goes beyond just a psychiatrist (to prescribe the meds) and a therapist (to administer therapy along with the standard advice about exercise and eating well). Something more like a "nanny" or a caretaker who could help the patient with those things: bug the patient daily to make sure they're taking their meds (and/or supplements, if you're going that route); buy and cook that nice healthy food; get you out of the house and into the gym; etc. Something more than just seeing a therapist once a week, but less intensive than any form of institutional care (even on an outpatient basis).
