I can tell you exactically what the song is about because I heard it from the horses mouth. At Kelly's "Behind These Hazel Eyes" concert, I was able to go backstage and see Kelly. When I asked her what (my favorite song) Because of You was about, she told me that she wrote it when she was 16, and it was "sort of a diary entry at first". She said that she comes from a broken family, like many children around America, and she wrote it about her parents divorce. She also commented that she doesn't think that adults realize the effect divorce has on children. She told me that she didn't want anyone to think she was sad or depressed - that writing the song was the way she got over the depression of her parents divorce. She'd gotten a lot of fanmail regarding the topic of divorce, and she said that she thoguht maybe God had her write the song in hopes that children who were dealing with the issue of divorce could relate to it; and, that the song could possibily help them like it helped her. She also said (in an interview - not to me this time) that she discussed releasing the song with her family and, although the song covers a painful territory, they also thoguht the song was better to be out -possibily helping people, than stuck in some notebook. Anyways, hopefully that helps.
