Worry with a purpose (write it down if you have time)
“If you tell your brain to stop doing something, [your brain] encourages it more,” LaRoche says. It's kind of like that old, "Don't think of a pink elephant" trick. That’s why she recommends making a list of things that bother you. “By giving your brain what it wants, you’ll worry with purpose, and eventually get bored of thinking about it.”
Make a mental note of the things you DO have going for you
Even if it doesn't seem like there are very many! For a quick fix in an overwhelming situation, remind yourself of three things that you appreciate about your life, or even three things that went well that week, LaRoche advises. This strategy helps replace what's stressing you out with a more positive thought (see above), even if it's only a short mental break.
