There is a saying that goes something similar to this:
“Give me the courage to deal with the things I can change, the serenity to accept the things I can’t change and the wisdom to know the difference between those two.”
In other words, try not to go crazy or obsess about things you can’t do anything about, there is no point and you will only waste your valuable energy in them when you should have a much clearer plan defined and putting that energy into it. Next time that you go like “AAARGH!” or “I can’t do this!” ask yourself in which two of the categories it falls, and then decide if you can do something about it or you can just kick back and relax about it.
There is also that other saying that goes something like this:
“Don’t worry. If there is something you can do about it, do it, and if there is nothing to do about it, don’t do anything. But either way, do not worry. Worry is useless.”
I say whoever said that probably never had to go through Reverse Culture Shock. Or maybe he or she did and that is where that saying comes from, from a very wise RCS survivor. In any case I find it to be terrific advice and I hope you can use it and make your life easier.
