Nice quotes

I'm trying to forget... that I'm addict,
I'm a dic... I'm a dic ted to u,
Heartbreaker... I'm a dic... I'm addicted to you.....

Tell me why... ain't nothing but a heartache,
Tell me why... ain't nothing but a mistake,
I dont want to hear you say... that I want it that way.....

You raise me up... to walk on stormy seas,
I am strong when I am on your shoulder,
You raise me up... for more than I can be.....


Can you tell me who sang these songs? XD
