car accident.. what to do

Hi everyone. so i got into a car accident couple days ago, someone ran red light and totaled my car. however they are not taking fault, i do have witness that saw her car hit me but there's no further evidence who's light was red/green. i file a claim w my insurance but i did get with a attorney already. i dont have major injuries but my car is gone. Any advice? If i don't get a settlement w my attorney can i still go under my insurance to see if they can give me something back? I havent spoke to my insurance since the day of the accident per my attorney told me not too. but how does this work? help
