If you feel like you are zoning out try these:
Hot and cold: 
Use water at different temperatures to help bring awareness to the body. 
Try holding hands in hot water, then switch to cold
let an ice cube melt in the hands or take a hot shower that ends with a burst of cold water.
5-7-8 breathing: Use breathing to calm the mind. Inhale to the count of 5, hold the breath in for 7 seconds, then exhale to a count of 8. Repeat as many times as needed.
5-4-3-2-1 method: Use the senses. Name 5 things that can be seen, then 4 that can be heard, 3 that can be touched, 2 things that can be smelled, and one thing that can be tasted. 

Create an anchoring phrase: Use a small basic paragraph with things that are known to be true, for example: “I am (name), I am (age) years old, My birthday is (date), I live in (city and or state), I am (current location, such as ‘at work’).” and repeat it slowly as many times as needed.
Think in categories: Think of a category such as state capitals or characters from your favorite book, and name as many as you can in one minute.

If you feel anxious before the thought or half way through it then let it go without any thinking.
If one of those anxious thoughts sneaks by your watch you can stop it immediately by switching to a positive thought.
If you find yourself in a cycling anxious thought and you cannot stop it then tell the thought to stop torturing you.
