Try not to worry too much Ashley, it is still early days yet. I think we all knew that we mere lower grades would struggle to get into the national events, but still being a reserve at least means they haven't told you where to go
I was a reserve at most nationals last year, and was offered a place much closer to the event.
So keep your fingers and toes crossed and make sure Jackie etc has the right telephone number for you!
Good luck, I am sure you'll get into some more,
