It's difficult to concentrate, I feel in a fog, shallow breathing and like I am going to fall asleep at my desk trying to type this out. I have NO anxiety; however, I look drunk when I walk and am not sure how to function like this. Is it possible that it will go away in a few days or is this initial reaction enough to say it's not worth trying? I can't seem to function at my job right now at all. It hit me while driving which is also dangerous.
