Put in mileage. Don't worry about it, just keep climbing as much as possible. You'll become more and more comfortable with the feel of using trad gear for pro, and it will get easier and more comfortable. Through repetition you can achieve focus.
But I always tell myself when climbing above gear: that people do this all the time, its safe, and nothing to get sketched about. If you need some extra motivation though watch "Hard Grit" and see british dudes taking huge whippers onto hand-placed pins, #1 RP's and the like. It makes fat cam placements feel super bomber.
