Thanks to all for the advice and words of encouragement. I was hoping to go flying tomorrow but it looks like winter is back....
I will keep at it, I do feel better today, and was really looking for confirmation that this happens to other people as well. I have wanted to learn to fly for such a long time that I have plenty of motivation, but my confidence just took a bit of a knock after sunday.
I will try some of the things you have all suggested especially the practice approach and landings at altitude. I'm also going to get my instructor to do the next landing and also to talk me through what he is doing and when, so that I can take my time to look around and try and appreciate the changing view etc.
Thanks to all the folks on here for your time!
