You can find them here. So this first verse is Avril talking about this girl and how she felt, but she doesn't say how this girl exactly felt because we will find that out later. But however this girl felt, she felt it every day. And it seems as though Avril tried to help her, but this girl wouldn't accept help. She just kept making the mistakes that made her feel the way she did. Then in this little pre-chorus bit, she says what people probably ask this girl all the time, "what's wrong, what's wrong now?". And this is a statement that people who are emotionally unstable get all the time. "What's wrong?" Well the thing about that is that there very well could be nothing really wrong. But in the song her response is "too many problems".
So by now I would guess that you have all figured out that this girl has some mental disorders (my guesses are depression and some anxiety and probably abandonment/commitment issues). And what I want you to get from reading this is that you're not alone. Because someone out there has felt the exact same way that you feel right now. And it's okay to feel that way. Because trust me someone cares. It might not seem like it right now, but SOMEONE does I promise you.
Love to all,
