Airgirl,
As IO suggests, tap up someone else at the airfield who is qualified and competent to fly in the conditions at the time and ask if you go along for the ride, offer to help with the Nav, etc.
Another idea is that if you get on well with some of the instructors ask if you can backseat one of their lessons, it will get you airborne and also its amzing how much you learn from watching someone else screwup!
