Hi! I just wanted to say don't fret too much. I am in a somewhat similar boat as you and working on the day to day struggle of accepting the current circumstances but not letting it affect my life to a great degree. I am 24 and just had an abnormal pap come back with HPV and mild dysplasia. I have scheduled an appointment next week for colposcopy and biopsy if needed - definitely nervous but trying to stay optimistic. You know, stress is inevitable (i know, I work full time and am a grad student full time), but it can be regulated. The way I look at it - give yourself a day or two to spazz out, since you know you will anyway. Then, calm down and say, "I know this is not the best situation but it's here until I find a solution so I may as well tackle it head on and just deal with it as it comes." I think maintaining a healthy attititude about the whole ordeal is almost as important as getting treatment. When you keep a positive outlook it enables your brain and body to focus on healing as well as on other things that you can do something about (eating healthy, exercising, shopping!). That's my take on it anyway.
I guess my point is to take a deep breath, relax, and see what happens. Whatever happens is gonna come along regardless of the about of worry you put into it. (I am a bit of a hypocrite on this though - who knows how many forums and sites i have researched just in the past day!).
Best of luck to you and if you want to talk or vent or complain or just let out some worries to an empathetic here let me know! :)
P.S. don't worry about the jerk guy. It's his problem not yours. You made the effort to inform him, if he wants to be an a** about it just let it go. :) You have more important things to spend your energy on!
