Working attitude

I feel that my working attitude have some problem. Not concentrate enough and no heart to work. And I feel really scared and tension about asking people around me. Don't know why that I still feel paise asking people around me when I have problems. People don't really talk and joke with me. Might be I'm too quite, thats all. Hard hard to communicate with them, I'm so scare and pai se. Hai~~

Where is my courage? Why am I scared? This worsten my performance in work.
