Mixed Feeling

Tomorrow,I will leave my hometown to start a new life over a place where I'm been there before.Really very sad,because need to left my family over here,instead of happy because can get an job in a big city.I hope everything will be fine and going smoothly according my plan.A thoundsand of worries have come to mind,because I'm just a new people in this field.My poor calculation in math,make me more worry about my future job.Can I handle a tasks that given?Speaking broken english in front of the collegue?Oh my god,really stress.But what to do?Life must go on,I just accept the job and keep on praying that god will guide me.
