they say there is a reason..

"They say there is a reason,
They say that time will heal,
But neither time nor reason,
Will change the way I feel,
For no-one knows the heartache,
That lies behind my smiles,
No-one knows how many times,
I have broken down and cried
I want to tell you something,
So there won't be any doubt,
You're so wonderful to think of,
But so hard to be without."
