(She's Already) in My Head

Don't you know Don't you know that nothing lasts forever Don't you know Don't you know that nothing stays the same She's already in my head, In my head And I'm stuck on those things she said, what she said But I promise that I won't wait around for you around for you Yeah I know there's still things I need to see Don't you know Don't you know that life don't go as planned Don't you know Don't you know you can't outrun the rain She's already in my head, in my head And I'm stuck on those things she said, what she said And maybe I'm just held up up on those yesterdays, yesterdays But I feel like there's things I need to learn She's already in my head In my head And I won't forget what she said
