Airgirl,
the very fact that you have this air of apprehension and concern tells me that you will be absolutely fine when the moment for going solo arrives. This feeling is not un-common, work a bit on the bits that is "worrying" you, talk to your instructor about your concerns, they will be alleviated and you will be OK, the most important thing is to enjoy every moment of your training, its all about enjoyment..... ooh,and when you go solo come back in here and tell us all about it..... just so we can say "told you so" !!
All the best for when the big day arrives,
Jon
