This sort-of started yesterday (not completely but this particular episode seems to have begun yesterday.) My wife & I were at a local tea shop. She was at the service counter & I was back at the table we had been sitting at. There were 2 or 3 other women standing at or near the service counter with their backs to me.
I was getting my coat on, since we were preparing to leave. I happened to look up a couple of different times & my gaze came to rest on one or the other of the other women in the shop. And for a "split second", so to speak, I was unable to determine if the woman whose back I was looking at was my wife or someone else even though they didn't look anything alike. It was like my mind just went blank momentarily. Then, after that brief moment, I was able to recognize that the woman whose back I was seeing was not my wife. It was someone else.
Today, everything seemed about normal

until mid-afternoon. I was mixing up some bread dough & became seriously riddled with anxiety, not related to anything in particular, & also quite dizzy. (As I write this, I feel like jumping out of my skin, so to speak.)

I've experienced these sorts of heightened anxiety / dizziness events in the past. I have Meniere's Disease & I always chalked them up to that. However today is certainly one of the more intense of these events I can recall having. And, coming on the heels of the experience I had yesterday, it makes me wonder what's going on.
I tried to see if I could find anything on the internet. But it was all beyond useless. Perhaps I should see a doctor.

But I'm doctor-aversive to begin with.

(I'm not on any med's of any kind.) Plus, I really doubt there's anything they could come up with given the subjectiveness of my concerns.
Yesterday I thought perhaps this is the onset of some type of dementia. But then, with the dizziness & anxiety thrown in, I wondered if I'm on the verge of having a stroke.

On the other hand, I'm not having any problem expressing myself here. Perhaps it may all just be something temporary that will pass. My experience, in the past, has been that this has ended up being the case.
