Donna,
I sympathize with your situation. I hope things work out. The first option I would suggest is to re-consider traveling. My first school I joined as a white belt was 8 miles away, and I drove there every day. I have traveled further, over the years, to train with a qualified instructor rather than attend a school that was within a few miles of my home. Continue to look hard. Something might be there that you have not seen yet, but if you can work out a long trip once or twice per week, it is better than no instruction.
Second option, continue to practice what you know daily. Work on basics: physical conditioning, strength, stamina, flexibility (keep stretching!), balance (if you have learned kicks, practice standing on one leg, and extending in all directions slowly). Work on focus and accuracy of techniques, and hang a bag for a heavy impact. I don't suggest trying to learn new things on your own, or from a senior student who is not likely qualified to "teach," because you will probably learn it wrong, and have a harder time undoing bad habits later.
Third option, read as many books on the subject as possible, and view instructional video tapes. Don't confuse this with "learning from books," but consider it research. Learn as much knowledge about the Martial Art as you can to prepare yourself for when your training resumes. In time, you will be able to determine what books and videos have something to offer, and which ones are full of nonsense. Don't believe everything you read or see, just take it in as objective research.
Last option would be to possibly find an internet connection to a qualified instructor. I know that there are some high ranking masters who will take on pupils through correspondence courses (just like colleges and universities do these days). For a reasonable fee, they will send you training material, and testing requirements. You send them video of your performance, and they will critique it, and reply with what you should do to improve. It's not the best option, but it is one option - - just be leery of frauds and rip-off artists.
Actually, I'm considering providing a correspondence course myself in the future, but I'll see how that turns out later.
Hopefully, something better will turn up soon!
Good Luck!
