I do love flying, but I must admit you begin to fear for your life more as you get older and it's worse now that I have a son because I worry about his safety too! If I get nervous I just think that although this flight is a big deal to me, and there's been a lot of build-up to it, it's just another everyday job to the crew. I imagine them hauling themselves in to work, going through the motions of the safety talk, the refreshment trolley, the duty free trolley, they have to clean up after us... and then do it all over again once we've left. I guess it's just putting the flight into perspective - a big deal to us but just mundane everyday stuff to others. Does that make any sense?
Hope you can relax and your flight goes smoothly
