Untouchable?

Don't you hate it
When you want something so much
And you can't have it?
When it's right there,
But you can't touch it?
When you can hear it,
But can't see it?
Or see it
But can't feel it?
I've heard people go mad
Trying to find love
But what happens when you've found it,
But can't have it
There with you?
