I am not an expert. My accident was five months ago. I am getting better but still have PCS. My doctor advised me not to drive until further notice. I would suggest talking to your doctor about driving and get a friend to drive you around. Other people on this site have said they forget what to do at a stop sign, or have difficulty remembering if someone is approaching on the left while they check for traffic on the right. I would also be concerned about your reaction time.

IDid you hit your head again? If not, then you are probably still recovering from the first one. In reading your post, it seems like you are having difficulty communicating clearly. The same thing happened to me. I texted my friend to tell her how I was doing. My texts did not make sense, words were spelled wrong, and she could tell I was in rough shape. It does get better but it is scary. Rest and take one day at a time. Your brain needs rest in order to heal. It takes a long time to get better-longer than you might think.
