What to do....

So, I've been trying to figure out what I should do when it comes to my schooling. I have pretty good grades, but at the same time I HATE school. It sucks. I try to suffer silently, but I just can't. I act as if everything is okay, and smile at everyone like I don't care, but really I'm obsessing over the smallest things and I get embarassed so easily. I try not to care about what everyone thinks, but becasue I've grown up in a home where appearances is important to everyone it's pretty hard to get out of that.
So my question is should I graduate early and get a full time job until college, or should I just endure another year of school.
I mean I don't care because either way I'll still be getting a job because I'm in dire need of one, but would it be worth leaving school early graduating without a my class and just cutting all old ties, rather than just sitting in 4 90 minute classes everyday for a whole other year?I don't know and it aggravates me so much because I really want to have my decision made soon so that I can make arrangements with my parents. I've been in the indecision rut for a while now and i just need to figure it out like now....
Oh well
that's it.
