kj, do you have any certain thing that you do to cope with rapid mood changes/racing thoughts? I do and I didn't even know that's what I was doing until my T pointed it out to me: I read or listen to music REALLY loud, oh and watch mindless TV (judge judy is my hero!).

I'm a reader by nature, so I read to keep my thoughts on something else. If I find myself drifting back to the thoughts I want to avoid, I reread the page I'm one until my focus returns to the book. I read an article once that said reading can be a narcotic for depression as it can become an effective and simple way to escape. So there's the downside, but it can help when you need it.

I'm also an avid fan of music, so I keep my ipod current and make playlists for my moods. If I'm depressed I listen to really up beat music, like what you'd listen to while working out. If my anxiety is high and I need to relax, I have a playlist for that, which has bunch of Enya music that would put most people to sleep.
And for me, it has to be LOUD, but that's just me.

And TV? well, that's just a guilty pleasure of mine. I flip channels til I find the trashiest show on at that time, and cuddle up on the couch until my mind wanders.

Figure out what you tend to do when anxiety is through the roof and try to turn it into a concious action. Of course this doesn't apply to really destructive stuff like drinking to oblivion or popping some pills, but you get what I mean!
You're in my thoughts!
