Oh! Golly, yes, of course you're right. And I should've known that. Rule One of ruminative thoughts is that you don't act on the thoughts-- you act to stanch the anxiety that enlivens the thoughts. I guess that even now I'm not really thinking straight. (Quelle surprise.)

I sometimes have success writing the thoughts out-- that way they may become "fixed" and I don't have to revisit them over and over again in my mind. Perhaps I'll spend some time doing that.
