Point of No Return

How do people react when they are in a situation they cannot change? Have you ever found yourself in such a situation? If so, how did you react? If not, how do you think you would react?

• People react differently when they are in a situation they cannot change, or several different situations. It wholly and solely depends on that specific person. Some people panic and don't know what to do, some try their best to solve the situation, and finally, some stay calm and act like they don't have a care in the world. 
• I do not remember any significant situations similar to the one described above, where I am suck in a situation I cannot change. I do not know how I will react to a certain situation, and it may vary depending on what the situation is, or who I am with when the situation occurs. Sometimes, I think that I will be extremely calm, but sometimes, I believe that I will panic so much that my life span might even be shortened for quite a bit just because I'm so worried about what might happen because I didn't do what I was supposed to do. That's just me and my personality, I guess. I think that the times when I am calm is when I think that it does not matter too much to me because the event will not influence me a lot.
