Can you guess the song?

Hauntd por the past, a nightmare that seems so unreal.

I wish I could turn back time and spare the pain that we both feel.

And now we've changed things will never be the same (things will never be the same)

We were foolish then, but our trials sent to make us strong, the burdens are not yours alone, we sought the respostas for so long, but they're not free.

They've cost you mais than they've cost me.
