I left school when I was 16 to go work in a factory,believe me it was the worst decision I ever made,leaving school.But somewhere inside me I told myself I need to complete school so I went back and graduated,best decision I ever made going back.I even went on to college.
I know how you feel about not wanting to go,I missed days at school because i felt so low inside.I just wanted to stay in bed and shut myself off from the world.
My advice is talk to your parents about how you feel and possibly go see a counselor to figure out why you feel the way you feel.
Do it before it's too late.
Just my two cents.
