OK, I need help.
I've been desperately trying to think of a song about a girl who is any one or more of the following
sad
lonely
mad
psychotic
in need of someone to care for her
It needs to have some sort of emotional trauma element to it.
It also needs to be dramatic, powerful. It can be gentle but it needs some moments of excalmation. Think Come Undone by Duran Duran but with balls.
Other themes that may inspire song choice are: birthday, locked away (metaphorically), broken childhood. Also, it would help if it's sung from a man's perspective (watching her) but that's a bonus rather than a necessity.
I'm certain there's loads of good songs with this sort of theme, but I'll be darned if I can think of any. Best song idea gets a cookie.
