How on earth do I make my life a lot better?1?!?!?

Ok so im a senior in high school and its just been a very stressful year! I live in Texas and you are required to p the TAKS test, i've yet to p the Math and Science subjects. So yeah im going to tutoring for that and all but its just so DEPRESSING because if I dont p, I dont graduate. THAN, I've been applying to colleges and stuff and i've been accepted to NONE of them! So bummer. Scholarships are another situation, i;ve filled out NONE!!!!! I just dont know were to start. =[[. My grades are ok but they could be better, im just to DARN lazy and tired! I ALSO HATE SCHOOL. I dont wanna be here so its given me a bad habit to skip, which I never did before. Idk my question is. What can I do to make my life a little smoother. PLEASE serious Answers. Thanks Jason-
