Does it happen to you? Because it happens to me. I become aware of my tongue. Sometimes I become aware of my whole mouth. It is indeed an awful feeling.
Sometimes, I'm even aware of my whole self. I'll be at some sort of event--usually one in which I am out of my element or I don't know anyone. And I'll become suddenly aware of my whole self...how I'm acting, how I sound. And the more I try not to be aware of myself, the more aware of myself I become. Until I feel both invisible and like fifteen feet tall at the same time. It's much worse than being aware of your tongue. But if there's just one person there that I know well and knows me back..then I can say something to them about how I'm aware of myself. And they'll either know what I mean or tell me how weird I am. And I'll realize that they're right. And either way, I'll feel better.
Anyway, I thought I'd share in case any of you are ever aware of your tongue, aware of your mouth, or aware of your very self. You are not alone.
