anton....
a very normal reaction to such a controlling environment.
public schools want to break you. they are charged with assimilating you into 'society'. they want to 'prepare' you for life. if you were not in such a trance like state at school you probly hate every minute of your time spent at school.
my suggestion is to start doing other things that YOU like while at school. write, draw, think, or read things that have nothing to do with your class, all while you are at class, but make sure you keep your grades up. you can easily study on your own and learn the info needed for your classes.
if you keep your grades up and don't make a ruckus they will probly let you do what ever you want to do, but if your grades slip....they will realize that you are not assimilating.
this is YOUR life. figure out what is right for you and do it.
find you.
be you.
f*ck them.
