When you lose in the game this does not mean freaking out, swearing and so on. Lose is very good. Because you grasp your vices and mistakes when you playing. In addition I don't recommend play a very long because you will lose touch with reality! Very important human's quality in gameplay is humility. If you lose in game, then don't break your PC or game console. You need a patience. Better you pray about luck to God. That you can play calmly.
