angry for nothing

back from the one-week field work. no easy job...but did have some fun. maybe will talk more about it another day. not today. i m very tired

tend to get even more emotional when i m very tired. if i m sad i will feel even more sad, if angry i will just feel like killing people. maybe it is just something not really worthwhile for me to be angry with, but still i just cant make myself to feel better. guess i m just too tired

there are a lot of things that i dont understand. maybe there is really no need to understand at all..maybe

i really need some sleep. good night
