PLEASE HELP WHAT IS THIS

SOMEONE PLEASe HELP I MADE OUT WITH SOMEONE A WEEK AGO AND I SLEPt with A GUY A MONTH ago. I really don’t want this to be herpes. It started off as a pimple above my lip and what seemed like a cold sore or cracking in the corner. The skin just peeled off the pimple as well as the sore and my skin continued to peel until the two were connected.

My dad comes home from a work trip tomorrow and is gonna kill me when he sees this please help!!!
