TCA peel 1 week before starting collage [Acne]

So im starting collage in 1 week and tomorrow i have my first TCA peel. Im very scared that it wont heal in time for my first day of school, i dont want to look creepy and off putting.

What can i expect from a TCA peel? Will it hurt? How fast will it heal? Will it actually look as scary as it does on the before and after pics?
