Many psychiatric medications exist, but since most of the things we group together as depression or generalized anxiety or others are some subset of a large number of possible causes, efficacy of these pills for any given person is rolling the dice, and takes O(months) to test a given med (for depression and bipolar meds, at least - O(weeks) per dose change). Plenty of people can testify to the efficacy of some of these meds for them personally, but even within families, having an immediate family member who responded well to a given drug is no guarantee it'll work well on you (though it's still better odds than without that data). Also, drugs+therapy leads to a better outcome, generally, than just drugs. So having more tools available, particularly a tool that improves the efficacy of therapy, is definitely a win.
