abnormal cells and now colposcopy!?😳

I have been getting Pap smears for a year now ever since my first I had abnormal cells and the second time testing after 6 months again abnormal so my doc wants me to get a colposcopy done at the hospital and I'm freaking out tgat I may have cancer.... has anyone been in this position before ? I'm really stressing that I cannot sleep and my colposcopy will be scheduled in around 3 months from now
