two things:

1. I have been awake eighteen hours now, no biggie, except that tomorrow I have a final, and a class.
what? you may say, finals are next week, and classes ended today!
yeah, apparently things like that mean nothing to bio teachers.

2. in exactly 4 months, I will be twenty years old.
Not a teenager.
I have a distinct memory of being twelve and imagining being a teenager, just a year away.
That was six years ago.
Ah, how the time flies.

now i'm a grown up.
