This is wonderful news!
I know what you mean about how you should feel more relieved but knowing that you have HPV will mean you have to be more vigilant about your check-ups.
And regarding why they biopsied you even though you didn't end up having dysplasia-- this happened to me too for the past 3 years. I had two biopsies (one in 2005, the other in 2006) and both came back benign, no dysplasia. But this year (2007) it came back as mild/mod dysplasia. So I know what you mean about having the cloud over my head. Even though I was relieved getting my benign biopsy results the last two years, I knew that it could change, and it did!
But you know what? Just going through all this has made me so more conscious of my health and what I can do to be proactive about it.
So it's great to hear you'll be keeping up with regular check-ups (I think it'll be every 6 months for you, right?) BUT also make sure to BOOST YOUR IMMUNE SYSTEM. I wish I had started my health regimen last year when I got my benign biopsy results but sometimes we need a little wake-up call (like dysplasia) to get in gear health-wise. So my only advice to you is to try everything possible (health-wise) to suppress the virus so you won't be needing more biopsies in the future.
Start taking supplements, exercise, eat right, etc etc and hopefully by your next pap it'll be normal!
So go relax and have fun-- congrats on the benign results!
