Brain Injury ID

i woke up around 6am on October 21 2015 with my arm round my wife just as i normally did but this day seemed different somehow. As I laid there trying to grab another 10 minutes of sleep, my wife moved as if didn't have my left arm around her.
That seem be a little unusual but I didn't think much about it at the time. I decided to go ahead and get up but when I stood up, I immediately fell to the floor with a thud because my legs couldn't support my 200 pound body and I screamed so my wife came running.. She looked at my face and gave me the F.A.S.T. and so did the 911 operator and the paramedics. Thing I would soon return to work, after 5 months I learned that a I never would.When I was learning to walk, I was stopped by the police asking if I was lost or casing houses. I later learned that I needed a brain injury ID card on me at all times.
