I agree with the general sentiment that more natural approaches are healthier and generally more rewarding, but some people really benefit from medication. Yoga, meditation, diet and exercise are really good at improving a person's mental health in the 4-10 interval. But people who are down around 0-2 can't "meditate their way out of" depression or anxiety, and they often struggle even to get out of bed, much less exercise on a daily basis. For these people, medications can really help. To say that SSRIs are bullshit just because exercise and a decent diet can clear up mild depression is folly.
