Contact an injury lawyer right away. No good comes from subjecting yourself to a recorded statement from a representative of the person who caused you harm. They are not looking to help you, nor are they seeking the truth. They are looking to hurt you and slant the tables against you. Talk with a lawyer who will aggressively represent your interests and put the heat where it belongs - on the insurance company of the person who caused all this misery and upset. We do so without apology or any concern what the insurance company thinks.
