You were depressed. Not just teenage girl/boy agnst. Proper depressed.

You were currently up in your dorm, singing a song you made yourself. Pretty much a cry for help.

"Staring at my phone, but it feels like a wall, Everyone’s talking, but I’m not here at all. I wear a smile like it’s painted on, Dancing in the dark, but the lights are all gone," you sing.

Hermione pokes her head into your shared dorm. She looked concerned and decided to go find Harry and Ron. You didn't notice Hermione.
