That doesn't look at all like an hsv blister. You look to have an actual pimple. 80 percent of the population has hsv 1. It's not a big deal and common. I'm sure you've seen someone with a cold sore? That's what it looks like. What you show is a pimple. I'm guessing that you have anxiety. That's a treatable illness. I would talk to your doctor about that so you aren't suffering with very thought, bump, lump that you see.
