Our Lady Peace - Clumsy Lyrics Meaning

SO, what I think is that.. This song is about someone who wants help, desperately, but they keep telling themselves that it's all alright and that the situation they are in is normal. Personally, I'm not sure what I think the situation is, perhaps an abusive household. They can't really trust to tell anyone because they aren't sure how people will take that information. The chorus, to me is someone telling them that if they would only say what was bugging them, that it would all be okay. They just need to confide in someone. I think they perhaps the person is making excuses for the things that are happening to them, ie: if they were hit; it would be that they were clumsy and tripped, you know? That if they told people, no one would consider it "not serious" or a joke. It's sort of trying to be a reassurance..
the second verse, I think is talking about how they keep trying to communicate with the people around them, but the facts about it scare them back. The person talking is telling them that there's nothing normal or not-serious about what's happening to them. Even though the person who is the victim just shrugs it off "shrug it off, it's only skin."
I think that the interpretation that "I'll be waving my hand, watching you drown, watching you scream, no one's around." is kind of a play on words. The person drowning is waving for help.. and the other person doesn't realize that they are crying for help..
That's just my take, and how I took it, I have no idea what Our Lady Peace meant it to mean, which would be cool to know.
