Depressed Friend RP

You're walking to a bus stop not too far from your house. Your car broke down, and you have to get to college before Dr. Pruneface, as you affectionately refer to him, calls attendance at 11:00.
As you sit down at the bus stop, you see a girl wearing black and white sitting next to you. She has cuts all over her forearm, and she has tears running down her face. At first you don't recognize her, but then you see her hairstyle.
You immediately identify her as Redstone, your best friend since first grade.
She's sad about something, but you can't tell. So, being the good friend you've always been to her, you ask her what's wrong.
