Not for You?

Not for you?
I'm not the one- you won't let me in.  
I watch your sorrow, and my pain grows.
I love you too much and nobody knows.  
I try my hardest to meet your growing needs-
to keep you up when you think you are beat.  
I try so hard…  
You fall so low,
I am not the one as you surely know.  
If I can't help you, I don't know who will,
but because you can't let me in…  
Then I'm obviously not the one,
but I love you still.  
If you don't let me in,
then locked up you will stay.  
Why keep pushing me away?  
I love you so much.  
Please don't leave,
you're the one I need.  
I love you too much- it's clearly seen.  
What can I do?  
I don't know but I may not be the one…  
But I still believe.  
That you are the only one for me.  
So, please don't leave.  
Let me in.  
Please don't cry,
if it's the last thing you do.  
I love you too much, to let you lay and die.
