Why can't you see me crying ?

Watching you go slowly kills me inside
To see the pain I suffer, it just isn't right
I find myself crying though you're still here.
One day you won't be here, and that's my greatest fear.

So I soak up the moments I had with you.
And regret the ones I lost when I had better things to do.
I know there are things I can never make up for,
And still somewhere inside I donn know if you loved me all the more

This only makes it harder to accept that you'll be gone.
How am I supposed to get up and keep moving on?
You've been here my entire life in many memories.
One day I'll make new ones and you won't be with me.

When I have a question, where do I run too?
For all of these years, that person's been you.
When I have a fear, who will chase it away?
I'm shrinking by the minute, dying by the day.

How many I love you's can I fit in before you go?
There will never be enough, and sadly this I know.
For the sake of my heart and the thoughts in my mind,
I'll say I love you, one final time..

But why cann you.......
Why ???
