It seems like you're having a lot of anxiety surrounding your diagnosis. I would encourage self-care, and research as much as possible from reputable sources. I think it will allay your fears some.
I was diagnosed this week with hsv2...this is my first outbreak...and between the flu-like symptoms and the pain, I haven't had time to even think about what the future will be like. But it seems that many people have this 1 in 6 adults, so it's not as rare as we may think.
You won't die alone as a spinster. This doesn't have to define you, it's just something you'll have that will flare up from time to time. I'm hoping the outbreaks will be less severe as time goes on, as I've heard.
I'm sorry you're having such a hard time with this. I was too, the first few days, now I'm just glad the pain is subsiding a little. Just take each day as it comes. Many people live with this. It's not fun, but it's manageable. I think there is literature out there, and even on this site, about how to tell potential partners about your hsv. I'm here if you want to message me!
