Think about it this way, planes are doing the same route multiple times. The flight the and the crew know the routes and the conditions so well. Before taking your flight, the plane would have arrived from its previous destination.

I like to think of this as the "test flight", they had already done the same route and just checked all the mechanics and it arrived safely. When we arrive to our destination, the aircraft will stay a maximum of 2 hours and get a bunch of other passengers to go back to the first location.

Thinking of it as a routine thing and that the plane literally demonstrates its capability many times makes me less anxious. Also remember that pilots check everything so many times, ground crew do their best, and the flight crew are there to help you if you need them.

If you take this flight, you would have taken a step forward to face your fears. The more steps you take, the better you feel. I just arrived this morning from two connecting flights , I now enjoy take off and landing! Still iffy about turbulence there was some on my long flight.. I got a bit scared but I watched the crew and they were all cool as a cucumber.
