I now know I didn't put anywhere near enough info down on the original form, I did ring and add about 15 new things, but the lady on the phone just took them down as bullet points, and I also have more info to use as well.
I still have no professional reports etc. but I have been keeping a diary (though only since Friday!) so obviously I can be much more accurate etc.
Can I just fill in a new form, and send it off?
