kaji,

It sounds like you may have become confused by your loss of directions. This can cause a loss of attention. Before your car is destroyed or junked, it may be worthwhile to have an accident inspector (police or state highway patrol or maybe your auto insurance company) look at it to try to piece together what happened. If you airbag went off but failed, you may have a claim against the auto manufacturer.

There is a saying, "Expect the best but plan for the worst." Getting a good inspection of your car will allow you to try to plan for the worst.

Your auto insurance policy often has a 'medical expenses' coverage. Is your health insurance running out or is it your auto insurance?

Amnesia just before and after a traumatic event can often get lost. The brain had not finished storing the information just before the trauma and the trauma caused the neurochemical process of storing that information to fail and lose the bit of memory. This same neurochemical process was struggling to return to proper function after the trauma so the memories from the time while this process is trying to regain proper function never gets stored in memory.

It is similar to when you have written a document on your computer but your computer crashes before you get a chance to save the document. When you restart your computer, the document is lost except for the part that was auto-saved by the computer in case of failure. This usually means the last 5 minutes of typing in the document is gone. Amazing how brains and computers have lots of similar processes.

You really need to be seen by a neurologist. Call and suggest that you may have lost consciousness before the accident and tell them about the October event. Or, an Urgent Care Clinic may be able to get you a quick referral. Try a doctors' office or clinic rather than an ER. The ER will likely say they do not see anything wrong and pass you off.

My best to you.
