KB Phil,
If your injury was in September of 2010, it is too soon to get approved for Social Security Disability. You can not get it until you have been disabled 12 months.
While you are waiting, download the TBI Survivors Guide at
www.tbiguide.com
Print it out. It has great information.
Don't get too anxious about your long term condition. There are many things that you can do to work past the symptoms. I have some serious dysfunctions but can still live a full life.
Tell us about your worst struggles. Hopefully, we can help you learn some work-arounds and accommodations that lessen the limitations you have.
My best to you.
