Abnormal Smear

I'm so full of fear right now I had a smear test 6 weeks ago, I never received my results but on Thursday evening I receive an email to say an appointment had been made for the colposcopy clinic for Tuesday. I just could help thinking the worst. I managed to get through to the colposcopy department and they had a nurse call me back to explain my results, she said I had tested positive for hpv an high grade moderate dyskaryosis. She explained I will go to my appointment have a chat, they will have a look and decide the best course of treatment. Right now in my head it's already gone too far and turned cancerous. I had a normal smear test 3.5 years ago. Can anyone share there experiences good or bad so I know what to expect.
