Ok, have spoken to DP, who is a police officer. He says there is no time limit on when you can report it. It can be years and years. They may well speak to friends. I am that if you have been left in that state the GP didn't question it, but at the same time he/she would be an excellent witness for you in court, and such damage would really 'prove' your point for want of a better way of putting it. You really need to talk to your local police to try and do something about this, they will also be able to refer you to specialist counsellor who will be able to help you in the long term, because after such an ordeal as this, you will need help, if not now, than probably worse, later. Sorry for sounding so crass, but it really is something you need to address. I am so sorry for you and I hope that you are as Ok as you can be.
