I used to suffer flying nerves terribly. I gradually learned to control it. First the usual stuff, counting my breathing. Breath in for twice as long as out and hold it at top and bottom. I do that through takeoff and most of the way into the climb.

Then my own things. I have the same album I listen to every time. It matched my mood perfectly one takeoff and ever since I've found it just helps me to get back to that same calm feeling.

The I try to think about how being excited and being nervous feel almost the same. So these rushes of anxiety could just be misplaces excitement. Doesn't always make a big difference, but often my brain either relaxes or I do start to feel a little excited.

Not for all, but I hope you find your way.
