Are there any professionals here to help me deal with my fear of flying - Turbulence?

Hey guys. I'm 14 years old and ever since I was 8, I've wanted to visit Canada. Downside..I have to take a 14-hour flight to get there. :/ I'm not scared of engine failure or anything like that because I know commercial airplanes can just glide to safety, or operate on one engine, or if a system fails because they have redundancies. But my biggest fear is turbulence. I used to enjoy it when I was little until a guy on the internet who identified himself as a reigonal airline pilot told me that turbulence can overstress the wings or fuselage, breaking them off, causing the plane to crash (the person in question referenced a 'BOAC' Boeing 707 flight in the 60's which tore apart in clear air turbulence) or turbulence causing the plane to loose flight controls (elevator, ailerons, engines etc. ) another is thunderstorms/downdrafts & updrafts, (never liked either of them on the ground, to be honest!) since it's transatlantic there MAY be a chance I'll have to fly through a thunderstorm. again, if that happens I'm afraid the airplane will not be able to take it, and come apart. I really want to visit Canada, I really do. cruise ship is not an option, as I get sea sick very badly. but now my friends know I'm scared of flying, they've been making fun of me for it, and making me feel more scared so I was just wondering if there's any real pilots within this forum to help me, because I'd sure appreciate it very much
