If you are afraid to fly, drive etc. and the feeling is that you are not in control, you may not be!

The inner ear controls more than balance, it works with your brain when you are in motion. The disorders are related to this

I am going to see my doctor in early Jan and will insist that the inner ear be examined as well.

I do not have trouble with balance with walking, but I can sort of see something odd there as well. My balance is not what it was 6 months ago.

Inner ear problems may be permanent or may be infections.

I did have symptoms of anxiety in my 20s, more like generalized anxiety for some months, so I do not think this is all there is to it. But it adds to panic symptoms.
