Does anyone get blisters on their hands when they're stressed..? ㅠㅠ

Lately, I've been working overtime so much at work that I've been working overtime like it's nothing, and now I have small blisters all over my fingers and palms. I went to the hospital and they said it's herpes, which happens when your immune system is low and you're stressed. Sob sob. It's so itchy at night that I can't sleep properly, and I scratch until it bleeds and stings. It's driving me crazy. Even if I apply steroid ointment, it only helps for a short time, and if my condition isn't good, it comes back right away. Is there no cure for this? If anyone else suffering from herpes like me can share some tips on how you manage it? I'm embarrassed to meet people because of my hands, and I'm depressed.
