Yeah, the cycle goes:

  1. be overly vigilant to a real or percieved threat for an extended period of time

  2. "threat-finding" starts leaking into regular life

  3. freak out about a normal situation falsely identified as a threat

The 3rd step resolves the whole thing, and is actually good (if nobody gets hurt!). That's a chance to take a breather and shine some light on the situation, or start the whole thing over again.
