I know, It's my bad. I still have a difficulty in handling my own mood. And it makes people around me confused. When I feel depressed, I will keep silent and keep myself far away from people, and yes, it take a very long time for me to get out from this condition.
People might confused because usually I always laugh when they throw any jokes on me. But now, I feel angry all the time. It is not their fault. It's my fault. But sometimes I like it when people don't get close. So I can be more productive and doing thing that is important for myself. Besides, I have many jobs to do, so I need to stay focused.
