Anxiety, at least medically speaking, seems to be a loaded word. I've been told I had "anxiety" for some health related symptoms I had experienced, though I feel nothing like excitement nor dread. It's a very strange thought...almost what I might call 'subconscious anxiety'. As in, I don't mind people and am not anti social. But sometimes, in large noisy crowds, would feel lightheaded as if were going to pass out. Never really figured that one out - just wanted to point out that anxiety isn't always just a person thinking negatively.
