Matt heres something to help you remain optimistic.
My mother in law had an aneurysm in her brain about four years ago. ambulance to the local hospital. life flight to a trauma unit. they got it all taken care of but said she would never regain her speech or motor functions. Today. she is almost perfect. She occassionally has a hard time with difficult or odd words that arent used very often but once she hears it or remembers it she's fine. she's also walking talking and driving as if nothing happened. Point of this story is just because they are doctors they are not all knowing. They make mistakes just like the rest of us. Thats why they have such large insurance poliicies. Keep your head up. go immerse yourself in your truck it will help.
