Oh then my take is that it's totally anxiety. My initial TBI was in August, and like you, I sought out a lot of help from this Forum which has honestly been a blessing (Sometimes a curse when I read too much and worry myself).

What would happen to me is people wouldn't seem real, the environment would just seem off - couldn't completely put my finger on it, but definitely off. Another member on here, qtipsq, suggested an excellent video:

I personally found relief in it because she is this wildly successful woman, experiencing the same daunting **** as me! It was nice to see that she overcame it and gave me a little...tiny...smidge of light at the end of the tunnel. Honestly, your biggest battle going through this will be against yourself. I strongly believe it's anxiety worsening the symptoms for you.

What has helped you in the past deal with stress inducing situations? Seriously.. this might be a little cheesy, but...Do you like to write? Meditate?

As far as going for a walk around the block, my suggestion is try to be with someone. It is a helpful distraction to keep you from focusing on feeling so off, plus it will give you encouragement to get out of the house.
