Should I ? Shouldn't I?

We've gotta learn from our past (especially our mistakes) to be better man each day for the rest of your future. beside mistakes, we should be trained more mature to handle every-kind-of situation. how to re-act? how to control own-emotion?

HORRIFICALLY,

when I'm in a middle that re-situation I just couldn't help my-own-self to react and not being overrated. every little things across mind was self injure, cry, anger, and everything turns out to be so wrong.
oh God, how to pursue my happiness? long-last one. I barely know myself recently and its pathetic. I'M TIRED! should I leave?
