First of all, I'm glad you're OK.

I used to work in insurance claims.

The accident is actually a "collision" loss, not a comprehensive. If she was carrying liability only and you don't have insurance (e.g. homeowners or auto insurance of your own) then her uninsured motorist coverage on her policy will fix her damages. As someone stated here, her insurance company might subrogate against you to reimburse them for their payout.
