Though it's not me

It's no question that the past had brought me here
Every single smile, Every single look, Every drop of tear
And I have no regret at all having gone this far
No regret that I lost a bright star
Instead, I am thankful for all that happened
Thankful that I lost a lover, a sister, a friend
I am thankful that you loved me and I loved you
Thankful for what happened between us two

And now that I'm here, I should feel happy
Though you lovin someone now, though it's not me
