Not uncommon I'm sure!
I went from gliding at a quiet unregulated site to learning power at Cambridge will full ATC. I remember that having flown gliders, I very quickly soloed, but was very worried that the circuit pattern would be changed during the flight as I found the regulated proceedure quite intimidating. It sounds daft really as the flying was easy, and the nav was no problem ... it was just the worry of talking and figuring the new circuit when I was so used to the gliding enviroment.
It will pass, so don't worry too much as I think most of us find one or two problem areas as we go.

PS ... I still hate the radio
