Thanks for your replies. I guess I needed some ressurance - this all happened after my class 2 and I didn't think about it until very recently and it's been bugging me ever since.
I don't want to hide anything and I don't consider myself as a dishonest person and all though I feel pretty awful at the moment Im pleased it's out in the open. I just hope they don't do anything too drastic.
Anyhow, lesson learnt and I will post an update once I know more.
