It may not be an option for you but I hired a lawyer to help me handle all the paperwork. The day after the accident my insurance agent called me and asked for my account of the accident and I immediately felt my chest tighten and needed help. A family member referred me to an attorney who was able to recommend a phenomenal lawyer in my area. That lawyer handled EVERYTHING for me. Every bit of paperwork required by the DMV, both insurance companies, the bank my car loan was through, the emergency room visit, the surgery to repair my arm and the PT I had to do. I did have to sit down with the lawyer and recount the accident but it was only once and he was very reassuring about it. After that every bit of communication about the accident was fielded by my lawyer. If I received a bill, a form, or any document related to the accident, my insurance or my injuries I scanned it and emailed it to my lawyer and never had to worry about it again.
If you can hire a lawyer I definitely recommend it. It removes all the weight of paperwork and the related stress from your shoulders and you'll know everything is being handled properly and on time.
