I also meant to say that when I had bad anxiety I was left with a kind of light headed feeling- I can’t put my finger on it to describe it but it felt like I was light headed but not dizzy if that makes sense?
I was off works with the anxiety for a good 3 to 4 months and it did go away in the end but it was some time going. As I said we are all different so it might be worth calling your GP to put your mind at ease?
