The Difference between I and if

If I ever had a cat, I would name her Yane.
If I ever am reborn, it too shall be in May
If I ever had the courage, I would have been a star.
What's the point of thinking all this, this far?

If I had that one phone call, I would call God
And say, Hey up there, now its your turn
Can we switch places? I'm tired of this fraud
And maybe now there are bridges I could burn

If I could see someone one last time,
That someone will be none but you.
So that I can laugh at your face, for
Foe, now I’m free, that’s the one thing true.

If I had that one chance
Would I waste it all again?
Or will I give it one last glance
And smile at all the loss, all the pain.

If I could sing a song
This would be the one
Of all the lost things on earth
All that’s between the moon and the sun.

If I were to exist again, will I take the turn?
Will I live a little differently from what I’ve learnt?
Or will I merely follow the path that once I tread
And enjoy that tear you cry when I'm dead?
