i was hit by motorcyclist ,who died and the wreck was his fault, i can''t sleep,what is considered mental anguish

Emotional distress is a difficult claim in North Carolina.  If you didn't suffer any physical injuries in the accident, you are going to have a difficult time recovering any damages.  You will likely need to receive actual medical care for your mental anguish - i.e., seeing a psychiatrist or psychologist, etc.  Without some expert medical guidance on just how the accident has impacted you, it is doubtful that you will be able to recover anything.  If, however, you have such testimony and treatment, then the extent of your problems, your medical bills, and other factors will be taken into consideration in determining the value of your claim.
