My husband says the same thing, definitely just a joke to make the mood lighter. I walk into furniture, walls, stuff I know is there but still hit it. Swing my arms into things and occasionally fall. I also have difficulty finding the right words to put in a sentence. My hubby gets frustrated with this and usually interupts and tells me to spit it out which just makes me mad. That also happens at work and I just say "brain fart!". Sometimes people get mad, other times they understand. Both these symptoms come and go. Just know you are not alone and hang in there sweetheart! I am not sure how to tell you to deal with it. It is really awful and frustrating, but if you ever need to talk, i am always here.
