I suppose you might include psychotherapy, various other non drug therapies, a whole range of activities, socialisation, sex, pets...

Most of those probably wouldn't be considered drugs at all. I think the jist is that you can get good results managing depression with a mix of treatments (that may include drugs), which will vary from person to person. I think it is similar to how HIV or high blood pressure gets treated. You need to find what works by trial and error.

I like the fact that in the above list it is not obvious where the lines are: drug or non drug, medicine, paramedicine, pseudo medicine, alternative medicine or old wives tale. That kind of blurriness also applies to the diagnosis of the condition itself.
