Oh, sweetie, I'm so sorry!! I'm glad you're okay.
Try calling your insurance company and telling them that you *need* a car. Better yet, call the woman's insurance company (since it sounds like it was her fault) and demand that they pay for a rental -- when I was in a wreck that wasn't my fault years ago, my mom called the other driver's insurance company and did just that and they paid for my rental car in full, even though I had it for more days than they actually allowed. Just ask for what you want, and be a pain if need be. From my experience, it's better to have the other person's insurance pay directly for what you need if it's at all possible. With my wreck, I got everything paid by the other insurance company, and I ended up being very fortunate that my rates were not increased.
Good luck!!
