Found cancer after colposcopy

Hi, 

This is really weird for me to be writing on here as it probably is for most of you. I had abnormal cells come back from a smear and referred to have a colposcopy and loop. Results came back that they have found cancer (a small amount) I am waiting on an MRI but terrified of the results as I don't want to be graphic but have constant diarrhoea and is obviously a result its spread, I have 2 wee boys and my anxiety is through the roof! I have to constantly talk myself out of panic attacks. I'm just looking for advice on how to best handle this situation or someone that has experienced something similar. Love to you all.
