Hi Maggie,
I haven't flown THOUSANDS of times, but hundreds, for sure. I sometimes still get nervous. But then, I think how (and this is TRUE) flying is MUCH safer than driving. There are THOUSANDS of flights every DAY of the year, and MILLIONS upon MILLIONS of people fly each year, and almost without exception, they all arrive safely. I've seen programs on television about what these planes can withstand, and they can literally bend the wings up to almost vertical before they break. These planes are SAFE and the pilots of GOOD and the computers are GREAT. Strike up a conversation with someone near you, it will help take your mind off things. Just try to relax, breathe, and try to enjoy the experience!!
