Digital,
Good luck with it all. It sounds as though you're just going through what everyone goes through.
The good news is it does get easier. However once your instructor realises you're getting on top of something he'll give you something else that challenges your capacity!
I did my first land away last week (dual) and I made a complete pigs ear of it - I was overloaded with the RT, nav and a new airfield and let it get on top of me. However I'm I remember only a couple of months ago circuit work was having the same effect and I never thought I'd be able to actually fly the aeroplane AND navigate AND use the radio!
Good luck and most importantly enjoy it!
