I think the real exhortation is to develop a multi-pronged strategy for managing depression. I didn't feel like my depressed life got durably better until I had both exercise and therapy, and there are still times where things aren't going well with no clear discernible reason. I suspect that adding a low dose of medication on top would help.

Every additional coping mechanism you add, that works well for you, provides defense in depth.
