I too have a bit of a hang-up when it comes to RT...
But since moving to France at least I dont worry about making mistakes like I used to. At smaller airfields I obviously need to speak French, and local pilots sort of expect you to be bad at the lingo anyway, so getting it wrong doesnt bother me. When I speak to larger ATC units I can revert to English where they are usually getting it a little wrong, as its not their native language, and it takes the pressure off me no end!!
So the answer is to fly over to France!!
