Songs about facing something you're really afraid of?

The seventh grade was rough, so I cyberschooled for eighth. But now, when school starts back up, I wanna go back to regular school for ninth. And I am terrified. I keep thinking that everyone will be mean to me and hate me and I can picture myself having an anxiety attack on the bus the first morning (I am especially fearing hate/meanness from people on my bus) and I am really scared. I know I need God's help more than anything, but if I could have some songs, too, (maybe at least SOME that are Christian?) that are about facing a challenge or obstacle that you're really afraid of, but you know going through with will ultimately make you happy in the long run, that would be great. Please no mean/rude answers, I am truly scared. Thanks in advance.
