Every step I have taken in the past few months has been a step away from pain, a step closer to feeling better. When I run, I know that at some point endorphins kick in, positive brain chemistry happens, and I feel brilliant. There is science behind that, obviously, but to me it is a simple equation that needs little explanation: I feel crap, so I run, and afterwards, sometimes for days, my depression lifts. It is not a magical cure, and I’m sure it doesn’t work for everyone, but it keeps a lid on it for me. I never expected running to lessen my depression and am surprised, daily, that it does. For me, it is truly a lifesaver.
