What is love ?

What is being in love?  

          Is it not being able
          to think properly all because
          the other persons name is
          in your head?  


          The fact that you cannot
          sleep without their aroma, so
          you ware their shirt?        


          How just the thought of
          that person makes you want
          to smile and cry at
          the same time because every
          second without them feels like
          a year?  


          How saying the exact words
          "I love you" feel like
          the hardest choice in life?

                           Is that it?  If so, then I fear I am.
