You should be able to drive it assuming your alternator hasn't gone bad, but the next time you turn your car off you're probably going to need someone to jump start you again.
If you have an Autozone or Checkers or anything like that near you, take the battery in and have them load test it. It should tell you it's resting voltage, cranking amps (CA), etc and will let you know if it's dead or not.
