Eveing, I think another issue here is that when we get ourselves worked up about 'things going wrong' powerful neurochemicals are released... you know, that endorphin/ adrenalin rush? That can become very reinfocing, because it feels good, despite the misery.

As I've become more aware, I can actually feel a carving for that in my body. For me, that's a good signal to do some physical activity and wear myself out.
