Yes, the Boeing safety issues are concerning but the odds of something happening on your flight are astronomically low. It's riskier for you to climb on a ladder to trim your trees or to be on the road driving somewhere. Check out your comparative odds of dying here[0]
The FAA claims that it's Air Traffic Controllers handle 45,000 flights per day [1]. That is only the USA. Any accident makes the news. So, do the math.
One thing that helped me was reading about the engineering that goes into the airframe of the planes. For example, no plane has ever crashed due solely to turbulence. The plane frame and wings are engineered to withstand massive loads, lightning strikes, etc.
