i have to carry on!

i've got a new job lately. the head of my department is a middle-aged woman, who is mean to most people. she is always unsatisfied with what i've done. i really don't understand. she seems to be that kind of person, who nerver cares about others. i don't remember how many times i tell myself: you have to be strong! but there is always some chance that i will nearly lose control. i can't help wondering if it is a right thing that i changed my job. do i have the courage to undergo all this? i don't want to be a person who complains a lot. i wnat to be a person who is grateful to life. i should be a person who is grateful to life.
