IMHO, this song is about the media and addresses journalists and/or critics. She simply explains how the way the media is treating her affects her.
I think that once you take this point of view you'll see that it fits the lyrics perfectly, but still, several comments:
"how can I complain when I'm the one that reaches for this" - she feels that she can't complain about the media's attitude towards her because as a pop star she has no choice but to expose herself to the public.
"because I cannot walk without my crutches" - the crutches could be a symbol for her music which she can't give up.
The school yard probably reflects the way Alanis sees the smartass critics.
