<human>: Give me a shortened version of the text

This is my first accident I've ever been in that resulted in dealing with Insurance.

This happened in Southern California, last Tuesday.  I was rear ended on the freeway when the flow of traffic stopped suddenly and ended up hitting the person in front.  Cops came, and filed a police report and the person behind me had already admitted fault.  I file my claim that same night.  I take pictures and notes and all that stuff I've read about.  My front head light is sticking out, and my back bumper is all mashed up, but the trunk still closes.

Next Morning I get a call from my insurance to discuss the accident and file my claim.  I follow up with him either that afternoon or the morning after and he gives me the insurance rep of the person who rear ended me (I have liability insurance).  I call the other insurance up and tell them the situation, and he says that this is pretty simple case and should be able to finish it soon.  He calls for a third party estimator and he ends up coming in on Friday and makes his estimate and says the other company will call me on Monday.  I make the call on Monday to get this payment for the damages going from this other insurance, and I don't get clear response.  I call again today, and i ended up talking to a different agent who basically said my car is considered totaled because the cost to fix is more than the car's worth.  

Throughout this whole process, I am still driving my damaged car which is apparently considered totaled. I finally start talking to other people about this and apparently I've been wronged.  I should have already gotten a rental car from the other insurance and that never happened and once i get this claim check they'll tow my car and I'll be carless.  I've also been told that my own insurance is supposed to be taking care of this claim.  

I'm so frustrated because I was told to keep driving and keep with my schedule, and if my car's damage ended up coming off and damaging someone else's car it would have been my fault.

What are my options at this point? and am I being taken advantage of because I'm naive?
<bot>: Filed a claim a week ago, still driving a messed up car that is considered totalled, and was never given a rental car. I didn't know I was being taken advantage of.
