Same thing happened to me back in 1989, but this lady blew a stop sign and clipped my back wheel. My face looked like yours and I had a concussion.
Her insurance company paid for the bike and they gave me a 2,000 dollar pain and suffering check. We didn't sue since she was a nice lady without a lot of money. We know her insurance would have paid for it, but I still stand behind the decision not to sue.
However, if she got cash, go for it. Old people need to realize that just because they're old, they are still lethal behind a wheel.
