I’m 25 and my first smear has come back abnormal

Hello,

I am 25, I had my first smear 3 weeks ago, the results come back today as abnormal, it states presence of high risk HPV and that on further analysis to the cells there has shown an abnormality known as high grade dyskaryosis (moderate). It sais that this diagnosis usually requires treatment and I've been booked straight in for a colposcopy on the 19th. I have awful anxiety (I have GAD) and I'm only 25 with a 2 year old and a 3 year old and I'm petrified! Can anyone share there experiences with similiar smear results and if the colposcopy is painful?
