It sounds like squeeky bum time for a while. I'm not going to lecture you, you sound like you know what you did was wrong and are learning from it, that is good. Most of us speed at some point, some of us get caught, I've been stopped 3 times and done twice. Once I was a nat's off a ban for the 100 on a motorway, it does make you think how you could live your life without your car.
I hope that this works out for you and you don't lose your licence but if you do take it on the chin and what ever do not drive until you get it back legally.
