Sleepless night

tonight my thoughts fly off to world where nobody sees me. I worry over my life too much really, well a girl like me who doesn't ? People say live in the present, i say preparw for the future. I'm afraid of big responsibility, what if i don't have a career? What if i was stupid i didn't past my exam? What if i become a homeless ? What if my family turn their back on me? What if i don't get into university? What if everything goes wrong? I'm a scared and truth be told i cry just to think of the burden of responsibility i'm going to face.
