Therapy?

I've recently found out that I have herpes. Since then I've been crying a lot and I've been getting a lot of anxiety. I went on vacation and upon returning home Don't wan to go out, I don't want to go to work. I just basically want to stay home in bed. The boy that I was with ended things and haven't heard nothing's from him which it's fine by me. With that being said, should I go to therapy and talk to someone about how I'm feeling.

I think a lot of the anxiety is coming from not knowing who gave it to me and the "closure" aspect. But I don't really know.
