So yes I have been stressed out however I don’t know if this is due to anxiety. I was checking out of the grocery store and I got this  random dizziness not just regular dizziness, but motion sickness like the room was spinning and I felt off balance I thought I was walking off to the side it felt. I thought I was going to faint.. I do have vertigo but idk I don’t think it was vertigo. So then my left arm starts to get numb and tight, and I have an ache in my chest. It also seems like I can’t my body is moving in slow motion and you can’t move  like I get stiff.. but I can move but it just feels like I can’t.. maybe I have low blood sugar or lack of iron idk but it’s weird. I was anxious to go in the store at first but that went away.. maybe it’s a combination of things. But has this happened to anyone else?
