Cover art for Madness lyrics by Alanis Morissette

I adore this song. Such a contrast compared to the rest of the songs on the album. This is Alanis realizing that her uncontrollable emotions can now be controlled because she understands where they come from and what can trigger them. It's like coming face to face with an addiction- you cant change without acknowledging your problem and finding the root cause. Alanis thought the madness was because of him, that it was something he would do or say to bring it on. But has come face to face with the reality that it was in her all along. So she thanks him for revealing the triggers and thus allowing her to manage her madness.
