Is my false confession to a DUI enough to convict me?

Was the passenger in a motor vehicle accident when we flipped several times landing upside down? I was not hurt but the driver was. A bystander was able I open my door and I was able to get out of the vehicle, the driver had broken his neck and couldn't move. There was no other vehicle or any property damage involved. 911 were called and upon arrival I told the police that I was driving. While the police were administering sobriety tests on me the ambulance crew was extracting the driver from the vehicle. We had both been drinking that night. The ambulance took the diver to the hospital, learning he had a broken neck. The police officer took me to the same hospital to get a blood sample from me. I was released at that time. Six months later I get a summons to appear in court. I was formerly charged with the DUI. The judge appointed an attorney for me. Upon discovery, my confession is the only evidence the state has to convict me. A confession that I gave with a b.a.l. of 0.19. Is this enough for the state to prove that I was driving? In my confused mind at the time, I was just trying to protect the driver that was obviously hurt.
