Is being afraid of flying an irrational fear? It feels very real, and even terrifying, for some people. Even though statistically you have a greater chance of being injured or dying while on the ground, if you focus on that one crash you heard of, and assume you’ll suffer the same fate, you can work yourself up into a frenzy.
Alternatively, if you start to focus on the statistical probabilities of a successful flight, and visualise that success, even through some turbulence and some bumps on touchdown, you can overcome your mental fear.
Relaxing and deep breathing can help. Visualisation is great. Positive reinforcement is very helpful too. With time and effort you can train your mind to overcome anything.
