Touching Class of Songs

Jilted women who lose their sanity.  Delta Dawn, Just Leave Me Alone (Ruby Red Dress).

Are there other examples?

I find these touching because this is (I think) a pretty common real-life situation.

Diana Ross' song The Last Time I Saw Him about a scoundrel who takes her money to set them up in the big city: "if there was nothing wrong, he would return right on that bus." is about a scoundrel and a woman so naive that she ignores her mother: "Mama doesn't trust him but he loves me, I can tell."

She is not crazy just gullible.
