Since it's a catholic school and all, please don't hate me for this.. Why don't you write a story about a girl who has lost all faith in God. Her life is horrible. She doesn't have any friends. But then, she finds God. (Let the angels sing in joy.) Her life turns out to be awesome, and she has tons of friends.
Not one of the best story ideas, but the only one I could come up with on the spot after reading your Journal.
WRITE ABOUT ONE OF YOUR SEX DREAMS INVOLVING ME
CAUSE WE ALL KNOW THERE'S LOADS ;)
I LOVE YOUUUU XOXOXOXOXOXOXOXOXOXOXOXOXO
