How is it that this recital has come about ? When you say you have a recital at the end of the year, is it the end of a teaching cycle year ( physcal year, so coming in June lets say) or years end for 2013, as in Nov/Dec ? makes a big difference how you have to prepare.
What types of repertoire are you considering and or know ?
Yes teachers interupt your playing. They are there to teach you how to play not to just sit back and listen to you play for them. Additionally, the more advanced you get then all the more they may be likely to stop you from playing ( reasons, things get more technically difficult, more to teach). A teacher can't teach you very much while you are playing the piano, they need enough to see and hear what you are doing. They aren't picking at you, they are teaching you and that's why they stop you, so you can listen to them.
There are volumes of books written about piano, confidence, even memorizing. Don't feel alone, they were written because people just like you and I have these issues !
So I gather you are 23ish now. How much influence are you expecting from your parents about this ? For instance, at 23 I was living on my own and starting a family and working career. Some today won't cut loose from the parents till much later. Parents are always an influence but at 23 I'd expect most of the control to be in your own court regarding a recital. The parents roll to be support.
