Waiting.
I’m always waiting.
  I lie awake at night waiting.
   I don’t sleep out of fear that I’ll miss it.
    I live in constant anxiety that I will miss what I've been waiting for.
  
    I’m also afraid that I’m not quite sure what I have been waiting for.
   I guess that’s why I’m afraid I’ll miss it.
  I guess that’s why I’m waiting.
I’m always waiting.
Waiting.
