I'm an avid bus/biker and it's very convenient and easy. Hopefully the buses in your area have bus racks on the front of the bike. Putting a bike on the inside of the bus would be very inconvenient for you and I wouldn't trust "the discretion of the bus driver." Many are nice but some can be really ornery even about the rack on the front of the bus!

I'm so sorry to hear of your seizure disorder. It's bad enough to have that and then suddenly not to be able to drive a car is another blow. But you may find that you really like bus/bike commuting. I certainly do and haven't driven the car since.

You can also contact the "paratransit" division of your bus company. By law, thanks to the ADA, bus companies are required to supply transportation to people who have trouble using their regular buses and if they don't have front racks, that would certainly qualify. Who knows they might even decide to add a rack to the route you would be using.

Good luck and keep us posted.
