Thing were left unsaid

Katherine has a dysfunctional family. Her father is an alcoholic, her mother is a drug addict, and her older sister, Ingrid, recently committed suicide. She was a straight A student, very shy, and always followed the rules. Now, she's rebellious, rude, speaks up a lot, and she's failing almost all her classes.
Will she choose the path that could possibly end her life, or will she turn her life around before its to late?
