Hi,
I got my ticket earlier this year and went through exactly the same thing. Things that helped me were:-
As much seat time as possible
Taking time to sit in the aeroplane and talk to it (Sounds a bit silly but once I had made friends with it I think we both trusted each other a bit more)
Circuits
Short trips
practicing the skills I had learnt, steep turns, stalls, PFLs etc as often as I could
Keeping in touch with my instructor
Working on my self belief... If much smarter people than me felt that I was competent enough to be trusted to fly an aeroplane on my own then perhaps should believe them.
You will have one awesome day in the air and it will all drop in to place
Hope this helps, If you want to chat drop me a mail
