Can you suggest a song?

A song that can relate to this:

Loving someone dearly but having to know that they'll never love you.

Or, loving someone and they do love you back but you're both too shy
to admit it :3

Thanks!!
(And any angry songs that allow you let your anger out would be good
right now too!)
Bullet Shaun: I have that song on my ipod :D It's funny although
slightly disturbing.........
