I voted for dark blue.
I've never been clinically depressed, but getting my positive HSV result was definitely one of the most depressed times in my life--in the top three (the others being the end of a 4 year live-in relationship and the death of my dog).
Anyway, I'd say I was quite depressed and upset for about 2 weeks. I was anxious, depressed, crying, and had a hard time thinking of anything except Herpes. But even as bad as that sounds, it wasn't every waking moment; I certainly knew on an intellectual level that it was not so bad, I still functioned in my life, and I did feel better very gradually each day.
Overall I was depressed for about 5 weeks, but I think it dragged out that long b/c I was waiting for test results for two partners and I was so anxious and feeling guilty, assuming I had infected multiple people (including the new g/f of one of the guys). I was absolutely elated when their results came back within a couple days of each other and both were negative.
My best friend and my regular partner, D., were really helpful to me when I was so upset. Both were able to listen to me rant and rave and spew endless Herpes facts, lol. And D. was really loving and supportive and never really freaked out about it, which made a world of difference, I'm sure. And, of course, finding HHP was tremendously beneficial. It was very nice during those early, insanely obsessive days, to have a dynamic message board (as opposed to just an unchanging list of facts) to learn all the details. And as I always say, I was surprised and so relieved when I stumbled into the Off Topic folder and realized that even people who had some tough Herpes issues actually had other stuff going on in their lives (wow, imagine that--Herpes wasn't ALL-consuming forever!) and could joke about things, etc.
