To try and answer the question ... our personal reaction to the physical stimuli of events around us is, perforce, personal. For example, I detest anything that tastes bitter so I cannot drink beer or coffee. Even the smell of these turns my stomach over. It has been like that all my life, my body will just not accept them (so spicy food for that matter) but I adore sweet smelling and tasting foods.
Likewise, I adore the take off roll and the moment of rotation. I can be in a really miserable mood but, the moment, the engines come up to power and the brakes are released - I start to smile. I no longer think about why some things are good for me and some bad.
If you are able to tolerate the journey by air - without actually feeling bad or panicked - then that may just be the way you are. If you DO feel frightened but still need to fly, then there are a number of courses and videos and do forth.
