Feel free to bounce your fears my way. If you need to talk. I know that you dont really know me, but I am a good listener. It is normal to be afraid. It is a natural human reaction. Has your GP recommended that you go and speak to a counsellor? Even if the results are good, it is a big scare, and you might need to talk it through.
I can give you my personal email address if you want it.

Take a few deep breaths, and remember your family loves you regardless.
