Now the reason we can't feel the Earth move is because the Earth is always moving at a constant speed--there is no acceleration. And when I first had this fear of the Earth moving, I felt that I was accelerating. But I was actually able to overcome that feeling just from knowing that this feeling is not true at all because of the fact that there is no acceleration.

But now instead of feeling that I am accelerating, the problem now is that I feel like I am moving which is true because we are moving and I feel that this feeling is well justified. This feeling that I am moving is causing me anxiety and panic and knowing that this feeling is actually true and well justified causes me even more anxiety and panic.
