What's the Difference Between Major Depression and Depression?

There are 500 thousand ways you could be depressed, and each one reuires a slightly different approach in its treatment. If we expand that to, say, scitsophrenia, which has many more symptoms, the number of ways you can actually be experiencing or displaying scitophrenia is actually seven trillion. That is insane in terms of numbers. We need much more, like, many more handles on how to treat each of these different experiences.
