There is basically nothing to go on from that description. All we know is you potentially damaged some part of the car and now it doesn't drive like normal. You haven't told us if you even looked under the car since you hit the ground, so there could be underbody panels hanging off or other obvious problems.
Please seek out a reputable mechanic or Chevrolet shop asap.
