Hypochondriac

I’ve came to the realization I have a herpes phobia? Every pimple/cut anything I think it’s herpes . 3 days ago I noticed a blister looking bump on my pubic area it didn’t hurt or anything it wasn’t even red. I touched it and it popped. That’s the only one I got it nothing really came out of it at all and it healed pretty fast nothing is there anymore. I was on my cycle days prior to the bump and do recall wearing tight underwear and the pads making me feel irritated, but idk if that could cause a blister? I’m aware I’d know for certain getting it swabbed but there’s literally nothing there anymore. If anyone could give me any honest opinions I’d really appreciate it.
