How to solve stress?

In my case, i yell, and scream. Someone thinks that ”What a crazy!” but if i dont harm them, i think it doesnt matter really. Koreans too much care about other’s thinking and have a regard for other’s feeling. Most important is oneself. we have to concentrate myself more than themselves. After then we can find who we are. However DO NOT FORGET you should not injure other people. Cause other is important for themselves.
