when you are angry
It's easy to feel so frustrated or angry that you want to disappear. I do, sometimes. But no matter where you go or what you do, your problems will haunt you like some rude spirit or bad dream. Maybe your problems will take a different shape, but they will be the same. So you have to look for them and find them. And then face them head on and win.
Someone smart once told me: sometimes when you feel frustrated, you should step out for fresh air. Because when a person is angry, it's contagious, and you end up getting angry at each other even though it's just the air.
So maybe open your windows.
