Hi and welcome, and yes I can relate.

I'm a TBI survivor; my symptoms didn't include problems with vision, smell or taste, but did include concentration and communication deficits, and I was also not able to drive due to physical problems and deficits in spatial processing. My in-patient therapy included occupational and speach/cognative therapy, sounds like occupational and speach therapy may be of benefit to you.

Recovery does take time, and 6 weeks isn't all that long in recovery from brain injury. It was several weeks before I knew what year it was, let alone the month and day. I was able to return to work part time 4 months after my injury, and full time 3 months after that.

I learned a new sense of gratitude for surviving my accident and for all the support I received. I wish you a speedy recovery and that you come out the "other side" with a renewed spirit, despite the current challenges.
