Emergency!! Cold sore

Diana • Not TTC at the moment .
Guys please please please 
This is my first time getting a cold sore! I need serious help. How the fuck do I get this off my lip? (Sorry for using profound language im just freaking out) 
I'm going out tomorrow and I had this two days ago but it just increased in size. I applied everything ! From witchhazel to ketchup. I bought clear cold sore bandages but then what else can I do? Did anyone try popping it ?
