Mom with seizures and driving issues

Hello everyone. I have been recently diagnosed with Partial Seizures and cannot drive for 6 months. I am looking for ideas and advice on how to get around. We live a large city but in the worst possible area for public transport. The closest trip to a grocery store is an hour and 15 minutes each way. I have two small children, ages 1.5 and 4. I have looked into taxies but you have to provide car seats and I cant carry them with us after we get dropped off. Any one have success with personal drivers? Is there networks of medical helpers that wont cost me a fortune? Personal assistants here run about $80 so that makes it WAAAAAY too expensive.

Can't wait to hear any ideas. Thanks!
