Visit with a friend and talk about things that are soothing.
Listen to, or play music. Sing, or sing along. Voice is very soothing to use in song. Partly it is the breath, partly it is the facial work to keep in tune, listen. I sing songs with my guitar by myself. Or find a friend who plays and we sing stuff we know.
Watch a movie that really grabs you.
I think we all need a "vacation" from our thinking processes...
