The rain/snow/ice can make driving a real bitch. The reminder in this story is to check your distances which can be tough in heavy traffic. Glad to hear everyone is safe.
Couple things to take care of. Write down your story. Write down every detail of it and have your GF do the same. When the cockroaches start crawling around refer to your notes (they will try to fuck w/ you). The adjuster from your company is not your friend (although he writes the checks so he kinda is) he wants to keep the bill in check and they usually will push to close out the Property Damage quick (and throw in the medical settlement right with it, in your case prob pretty limited). Be thorough take what ever pictures you can (vehicle,seat belt rash ect) and don't tell anyone shit (other person, their ins co, their attorney,adjuster) and its time to get prepare for the after effects
