Limbo
There is no one word, of any phrase, in any language, that can describe the way it truly feels to be heartbroken. The feeling of heartbreak transcends human thought. You feel it surge through you in waves - as if you were a black, tar road in the midst of a desert heatwave. It's an ache that pulses through every layer of your being - first, as a numbing coldness that trickles across your skin... then, as a crippling tightness that travels through your muscles and stops your heart, and again, it strikes; as it frictions through your bones. It doesn't stop there - to be heartbroken is more than physical. Heartbreak happens in your body, your mind, and your soul. It's a darkness that infects you, and consumes you, after beating you down to the point where you can no longer stand. It's a sting in your chest - and a magnetic pull in your soul, towards someone or something that can never have you; one that earthly and physical barriers prevent from ever being satisfied.
There is no such thing as heartbreak. For to be broken by someone that you love, or who once promised to love you, is to have every fiber of your being put in limbo - neither alive, nor dead... just floating, unaware, unfulfilled, and purposeless until you are either swallowed by your demons, or rise again to feel warmth and love. Some people float forever, some for a while, and some never do realize that they are still numbly in between happiness and depression...
