It's important to find out what's bothering you and fix it. Like lately I felt the same because a colleague at university was seriously slacking off in group assignments. However, I don't want to be "the guy who tells on other people" but in the end that just harmed my own well-being. Now I fixed the situation and it feels much better. So all in all I'd say; try to find what's wrong and make sure that you fix it. Good luck! 祝你好运！By the way, is that L in your avatar?

in fact , when that happend to me , i go to pray and read som" quran " , cause that help me to relaxing and to think more about averything i do it after that ........so u shuld be think more about averthing u do and blieve ur selfe cause that so important to make u feel better....and don't care about anybody , just do the right think without fearing another people .... :)

Bill Tan is right. you cant do or think straight at that time. so try to rest and cool down first.

Stop doing anything, rest for a while before thinking what happens. Then move on...
