So these thoughts and feelings are very real for many. You have a few suggestions. I recommend that when your thoughts are racing, think of the wheel of a bycicle when jacked up in the rear and the more you spin it, the faster it gets. So, if you stick a cog (or stick) in between the spokes what happens? The cog makes the wheel stop. So, use this analogy and identify at least 3 “behavioral cogs” in which you will use to stop the racing thoughts or anxiety. One behavioral cog may be counting from 50-1. Counting backwards uses a different part of your brain. Also, someone mentioned both imagery and deep breathing. You must find what works best for YOU and be consistent. You’re a fighter cat so, you know how to get a job done!
