Good post and good questions. I always remind myself that although that moment it may seem bad it will all pass in a short time and the thing that will most likely make it last longer is my hanging on to the issue. Whenever I mess a flight or it is delayed and causes me to miss another flight I always say that God did not want me on that flight. I might have been that extra weight that caused the crash and that is why I was not allowed on it. The key is to turn it into a positive in some way so you do not develop stress. There is a statistic I always keep in mind. When you worry about something, there is only a 16% chance of that happening and out of that 16% you only had a chance of affecting it half the time meaning you are getting upset over something you only had an 8% chance to change. So if you are late and missed a flight or if the flight you are on is delayed and you miss your connecting flight, you cannot impact what happened, but you can control your attitude which controls your stress levels. Thanks.
