I'm freaked out about turbulence?

Next saturday I'm flying alone with attendant from OKC(Oklahoma City,Oklahoma) to FAI(Fairbanks,Alaska) I have 2 stops 1 in MSCAA(Memphis,Tennesee) MSP(Minneapolis St.Paul). Anyway on the news I saw this plane that was flying and had such bad turbulence they had to make an emergency landing in Miami,Florida. I fly alone all the time. But when they asked ppl questions they sad ppl were praying and getting thrown out their seats. I'm really freaked out what are some things I can do on the planes that will keep my mind of this??
