The best advice that I recieved when starting out in aviation was "it takes at least 6months to feel comfortable and a year to feel confident". You know what, it's true. I am ground staff for a British carrier and remember well feeling overwhelmed by it all. The a/c configs, the airport codes, the calls, the different codes for different gates, the different check in types, the shifts! Now I love it and I'm coming upto five years now. I would strongly advise you confide in someone more senior who can help you with the adjustment. They have been there too and will want to see you succeed. Good luck.
