I agree with Pretty.Like.Drugs - I think it's probably about mental illness. Katie Jane seems to portray a lot of the symptoms of Asperger's Syndrome or another high-functioning autism and the lyrics could represent how she feels about the illness (if she is indeed ill - It's by no means definite - She's never stated it or anything... but from the way she acts and speaks, it seems likely).
