Can I ask for rental car reimbursement after a car accident?

I was in a car accident, which resulted in total lost of my car. The other person was at fault. The insurance company did pay for my car, but doing the procress of them paying off my car, I now have to rent a car, due to I have to get back and forth to work daily. I drive almost 100 miles back and forth to work everyday. I now have to buy me a new car, which I don't have the money for a downpayment due to my credit isn't good and also I can't save enought money for a downpayment because every week I am renting a car for almost $200. I can't afford to miss work, so tell me can I add the rental car payments into my law suit? I still have to pay my bills, take care of my kids and plus rent a car. This has put a financial drain on my income and pockets.
