nope, don't move out just yet...hang in as long as you can, at least til you're out of school. BUT, i agree, if you don't already have one, get a part time JOB!! JOB = $$ = Parents with much less control.
I went thru something similar just a few yrs ago myself, ended up moving out just before my 18th day, but thankfully had a full time job and had been outta school for a couple months. the last six months living with my folks were hell on everybody, hence my leaving when i did...but what made those last few months bearable for me was having a job, so i had my own money and really didn't need my parents for anything other than what they were *legally* required to provide, ie. food/shelter. remember, pretty much no matter what you do, your parents can't boot you out until you're 18. don't get me wrong, you should respect your parents and follow their reasonable requests...but you don't have to be their bitch anymore either.
funny thing was, after i first moved out i didn't talk to my folks for a several mths even though we lived in the same city, maybe 10 miles apart...but after that initial "scare" they realized that what their beliefs are and whatever my beliefs are, it's not worth losing a family over, and now we're closer than we've ever been. of course, i was never baptized, so that helps b/c there's no shunning...
anyway, stick it out, but stick to your beliefs...who knows, your parents could come around one day
