I have to admit this has never come up before in my 30 years of involvement with the legal profession. I have to wonder what "options" you are "out of." (Waiting until the last minute-- "I'm turning 18 tomorrow" --seems to indicate a possible tendency to put things off.)
if there is a counselor at the high school talk to them. If you are really trying to turn your life around someone will help.If you are a major problem child... you may be less fortunate.
I agree with the previous responder that this question is unusual. An unusual situation sometimes requires an unusual response. To that end - and this is outside of my expertise as an attorney - it occurs to me after you reach the age of majority and you are no longer a minor, the law most probably would view you as tenant residing in your parents home. If so, you would be entitled to all of the rights of a tenant under the law.
By this I mean that if you refused to leave upon request, your parents most likely will need to properly and legally evict you from the residence. While this is obviously not a long term solution for you, allowing the eviction process to proceed will buy you some number of months to prepare for a move, rather than be on the street this Saturday. You may want to consult with an attorney who specializes in Landlord/Tenant or Unlawful Detainer to get more information, but it seems like you have nothing to lose, so demand to be evicted.
