To me, the best solution currently seems to be some combination of meds & psychotherapy. When they work, the meds can assist with the process of re-evaluating one's mental perspective & help stabilize a hopefully better mental state. However psychotherapy (or at least, being able to talk frankly about one's troubles) seems likely more effective at rewiring one's thought processes than meds alone.

Basically a lot more work needs to be done to make treatments more directed, effective and last, but not least, readily available & affordable.
