Visual deficit

Well, 2012 is not going out well for me. I had therapy today and all of my therapists plus my hubby put there heads together to figure out why I can no longer walk. It appears I have a visual deficit. When I stand alone I get terribly dizzy and freeze up. However, when hubby stands in front of me and blocks out all visual cues I am ok. My theripist tried it, but she is shorter than me and I couldn't move.

Whatever it is, it is extremely frustrating. I can tell myself a thousand times that I am ok, but my thoughts can't overpower my brain no matter what I do. My tone takes over and I am helpless against it. Twice I have frozen up and hubby has had to rescue me. I could barely make it the three feet from my chair to my wheel chair. It frustrates me because this has come on all of the sudden. One day my gait was improving, with the walker of course, and the next day I had to revert back to using the wheel chair. It feels like hitting a brick wall. Beyond that, I can't even enjoy the improvements in my hand because this is all consuming and has taken away all the freedom I have had. I am now trapped in my wheel chair which is extremely uncomfortable. It has been 4 days since I could walk alone, and I was doing so well. I even made it down the two steps to our garage on my own power using the bars hubby installed, but now I can't walk under my own power. It warmed up today and I had to sit inside and watch the rest of my family play in the snow...warm is anything near 30 degrees.
