If you are telling us the whole truth and there is no other criminal history (depending on the state this occurred), you should end up getting a PreTrial Intervention/Deferred Prosecution Agreement which will likely lead to a dropping of the charges once you've completed all of the court's requirements. Expect a fine in the neighborhood of $200. We would recommend contacting the Clerk of the Court and find out who the Public Defender would be in your case. Write them a nice letter outlining your fears for having a record at this young age, you are a conscientious student that made a critical error in judgement. Let them know you are aspiring to greater things and hope and pray for "an outcome that will not erase your dreams." With a little luck, this nightmare will be behind you in 2-3 months without affecting your life down the road. And, stop driving around with weed, smoke in your home.
