Herpes...I feel ashamed

I have herpes and I have no idea who I got it from since it showed up when I was in a long term, monogamous, faithful relationship.

I feel like I'm tainted....like I'm damaged and dirty...I'm embarrassed by it and ashamed. I don't know how it happened (possibly had it from mom at birth) but now I have to live with it. And I'm scared.

How do you handle the society stigma towards herpes? I know it's easy to manage but how do you deal with the fear of rejection? Because you're considered "dirty" by society?
