Well, I'd:
1) FREAK OUT
2)Stumble around blindly because my glasses don't fit
3)Panic about my enlistment
4)Try to sneak out of my room into the bathroom so I can look at myself in the mirror
5)FREAK OUT
6a)If everyone else in the world changed too, then I'd calm down, chill, and try to see what my friends looked like.
6b)If only a select group changed, then I'd try to approach my parents and explain what's going on, then try to avoid media, scientists, and the government; which wouldn't be too hard, since, you know, Alaska.
6c)If only I changed, then I'd once again freak out, calm down, pack a bag full of stuff, then escape and evade out of Anchorage till I was safe then live out in the wilderness and hope for news of others like me.
