Running every morning is the hardest thing to imagine doing when you're depressed. The worst part is that it works.
You're right about it being more about management than "overcoming". I've also found, and heard others say, as you get older it naturally loosens its grip a bit.

I went looking around for more info about MAiD after this post and found this. (I'll fix the link as soon as the bot scolds me).
I can feel so emotionally empty sometimes, but watching this video, the part with Orlando Da Silva in particular, I recognized in him exactly how I felt from about 17-27. I could write paragraphs right now about the ways I know he felt just from the micro-expressions on his face in a <1 minute interview. I had tears streaming down my face before I even realized I was feeling it. The weak half-hearted arm gestures and the defeated half-mumble as he felt the energy sucked straight out of him talking about his treatment. It just caught me off guard.
I don't think I have a point here beyond "I had an intense reaction to this and wanted to tell someone."
I know, I am/have been in the same situation as OP. I don't want to sound like a rise-and-grind guy, but when you get a little relief it's something to keep in mind. It will make that period when you feel okay last a little longer.
