I know how you feel mate I had my old Starlet wrote off by some old numpty a few months ago, similar sort of situation I was on a main road they pulled out of a side road without properly looking and tried to say I was speeding (I couldn't have been, I'd just gone past a speed camera), but I ended up quite lucky, kept all my mods, got over £1100 back from it and it was only a Sportif. Don't waste any time getting onto the insurance although I'm sure you already have. Get everything done a.s.a.p and make sure you can easily prove that they were in the wrong. My insurance took about a month to sort out, for a few weeks I heard nothing then I had a letter saying the other party's insurance admitted liability, I got a cheque through a few days later, then took me ages to look for a car and I've ended up with a nice CRX.
