ive pierced my lip about 5 times.
exact same story as you. i had one hole on the outside but it never went through right so i was left with a bunch of holes.
the hole will heal nicely so dont worry about it.
it won't leave a scar.
youll have giant bump for 3 days. put ice on it right now, and then leave it for a little while. then do it again. do it when you go to school, get home from school, and before bed. it should go away MUCH faster.
i only iced it once a day. and i had a huge speech the morning after i pierced it. it was horrible. just curl your bottom lip in and it wont be so obvious.
also, bite the bum/chew on it.
that makes it a bit more sore, but does soften up the skin instead of it being blown up and stuff.
dont worry about it since it's a friday.
itll be back to normal on monday if you ice it a lottttt this weekend.
goodluck~
