I agree, RELAX and if in doubt speak plain English.
Too many ATCs pass too many pieces of info for repeating in one transmission in any case. Three is supposed to be the maximum, but it is frequently nearer ten, and frankly you can only remember all that if you have a pretty good idea what they were going to say in the first place.
With practice it will become much easier.
My wife recently did her PPL and had the same sort of problem, but managed to get quite a few laughs out of the ATC when she asked for re-entry rather than re-join.
Listen to some of the "commercial" transmissions and you will find even they can get it wrong "er Er Speedbird 13 Quebec, oh no sorry I,m a Shuttle today" etc etc.
Good Luck
