I had a 6 year lay off and the first hour back in the aircraft was dreadful! I felt comfortable keeping it straight and level but my speed/pitch control in climbs and descents was awful! It took a couple of circuits to get ahead of the aircraft but about 6 hours of GH and circuits before I was happy enough to go off on my own. RT was fine although I did my revalidation in the US after doing my initial flying in the UK, so it took an hour or two to get used to the differences in the RT and airspace etc.
I don't think you need to worry about looking daft in front of an instructor. I am sure they have seen it all before!
