you seem like really anxious about your job wor........i know you are responsible person....and ur work give ur a lot of stress.............during ur working hour .....you think about ur job which is good!! but after u get off from work.....try to do sth u like.......so that ur mind can be relax .....such as playing w/ ur QQ dog .......for me.....i feel relax when i am in church..or pray....being w/ God , i can feel peace ......if u hv time.....try it la......hope u feel better la....!!!
