This accident was not your fault, don't let it be. Make the insurance company pay for everything, time off of work, Dr.s bills, broken pencil, EVERYTHING.
Now that your car has been in a wreck you need to tell them it is worth less than it was before and they need to compensate you for it. You need to look for diminished value in addition to the repairs.
My car got totalled and I got paid the value of the vehicle, which could not replace the vehicle and I got screwed. I was young. If they balk at the #'s you throw at them, ask them if they know any good lawyers.
