Wake up man

In a train feeling sleepy, but don't wanna go to school. Just lying in a seat and lost on thinking the problems inside me. 
Nowadays i'm in various problems that i haven't found solutions inside me. Trying hard for best future. Life in japan as a foreign student is much more interesting but need to manage everything by oneself. I'm having test tomorrow but without confidence i can't handle it. I had done well in last test but there are so many obstacles behind tests and life so wanna 乗り越えたい everything what come ahead.
