Hogwarts Frozen

Intro you: any gender, Gryffindor, any name, ice powers. (just add the character) story: you've lost control of your power even if you're wearing gloves and you lock yourself in your dorm room. the room was completely frozen. you won't let anyone touch ypu because you're afraid of yourself. everyone has tried to get you out for days but you wouldn't. (it's basically like frozen but a bit different).
