The thing about most mental illnesses/disorders is that the bulk of treatment involves therapy and lifestyle changes, both of which require patient compliance.  Meds are (supposed to be) just to get you to a point where you can do that effectively.  A lot of the frustration surrounding mental health care is expecting it to work like treating a broken bone (set, cast, let heal; heals completely in time) when it's more like treating acne (skincare regimen to reduce symptoms; maintained indefinitely).
