I don't really know, but it's worth a shot right? If nothing else.. it might help minimize it, or break you out of the worst part of it.
When I'm in the middle of a depression... I find that my students are probably the best thing for me. They make me be active and attentive and they force me into doing things. Sure, I go home utterly EXHAUSTED and might not do much of anything else... but during the day? At least I'm occupied.
And if I can get my own sorry butt to do something that's relaxing when I'm in an up? Like playing a video game or reading or something? Yeah... it'll slow my brain down a little bit. Might go from one relaxing thing to another in quite a quick procession... but... still, it's a little different.
Then again.. sometimes neither of those things will help at all. But it's worth a shot
