Big ugly cold sore!

I'm bummed, I have a holiday party to go to Friday night and My husband and I are hosting a big holiday party this Saturday and I have a big ugly cold sore.
It started Tuesday morning. I put ice on it and went right to the pharmacy for some Abreva after work and have been regularly apply it.

In the grand scheme of things, I realize a cold sore isn't that big of a deal, but since it's the biggest issue for me 'right now' - I'm bummed that any photos of me will have a swollen lip with a big ugly cold sore on it.

I hear other people get cold sores but it seems like I don't see them around and do wish I could hide my ugly cold sore at home.
