"I will be doing an internship at Lufthansa CityLine Technik in EDDH"
I'd relax and see what opportunities this may bring, who knows.
Definately come to the states to get your tickets though, its much less. I hear we'll have user fees soon but it can't be as bad as it is in Europe.
You've got time. Get an education in something other than aviation, relivant but give yourself a back up. Don't stress to much about it and fly the bones off your flight sim for now.
Stay focused, good luck!
