my instructor assured me not to worry as it was my first nav flight,
He's right; try listening to him! And think about it. So far you've been able to concentrate 100% on flying the aircraft, with a bit of radio work thrown in. Now, suddenly, you're trying to do that, plus work out where you, where you're going, how to say some unfamiliar things on the radio (not just "downwind" or "request taxi" any more), and how to juggle a cockpit full of bits of paper. On top of that you had marginal weather, and a crosswind landing. Now, Maz, read that as though it was someone else...doesn't it sound like a rather steep learning curve? But don't worry, as with everything else in flying, it'll get easier as you get more used to it.
