When Little Things Become A Challenge.

There is this constant pain I feel. It takes me over, body and mind. When I find myself alone and able to be with my thoughts, I begin to feel it. It becomes hard to breath, it would be easier to stop breathing. It feels as if I should cry but if I were to loose control the probability of me getting control again would be nearly impossible. It's all so dramatic, yet it's constant. I have two extremes, no medium. I can be at the height of happiness and feel completely safe and secure. Or I hit bottom and feel this uncontrollable sorrow. I feel like I'm alone in this. There should be a medium in there somewhere right? Shouldn't I be able to roll with the punches by now?
