Why do you feel that way? What happened? How are you going to change it or are you even going to try? What does it feel like to wait? Where are you waiting? How can you even tell that time is passing? Why do you wish for that person you wish for, and why will they never quite be yours?
Two or three words in each line is not enough to express what you feel, at least in most cases.
You have a good start, a great start even. There are places you could go with this concept. Now, you've just got to go there!
P.S. Sorry for the generalized unhelpfulness. It's the best I could do.
