Once your body is allowed to return to normal functioning levels, it actually responds with a swing in the opposite direction. So, those cortisol levels that were so elevated are likely now dropping BELOW normal levels. Because all the neuro-chemicals in your brain interact (lowering the level of one will result in elevations or decreases in the levels of the others), thus wreaking havoc with all your other neuro-hormone and neurotransmitter levels. The mood changes are a signal that the pendulum swing has begun. As frustrating as it must feel, it is, in fact, a good sign - it means that your body is in the process of returning to equilibrium after a time of prolonged stress. In the coming days and weeks you should notice a decrease in the moodiness and a return to your old self.
