Here is something worth knowing early on: your anxiety isn't lying to you because it's broken. It's lying to you because it's loyal. It would rather be wrong a hundred times than miss the one real threat.
That loyalty is exhausting, and you're allowed to stop taking its calls on demand.
The Kettle Rule
The next time a worry arrives — the email you haven't answered, the thing you said at dinner — put the kettle on. Don't argue with the worry. Don't solve it. Say, out loud if you can, "I'm having the thought that…" and finish the sentence. Then wait for the kettle.
Why it works: those three minutes create distance between you and the thought, a skill psychologists call defusion. Most worries lose half their grip once they're named instead of obeyed.
