When thoughts keep coming

Hi coaches,

In conversation today my husband told me something I found worrying. My brain immediately latched onto it and started feeding me lots of scary thoughts. I consequently felt fearful .

As soon as I could, I put everything I was feeling and thinking into a model and felt a bit better afterwards. I carried on with my day but noticed all the scary thoughts kept on flooding back into my mind. I remembered the thought from my intentional model which I kept repeating to myself. The scary thoughts would die down a bit but gradually return. Again I would recognise my brain was once again trying to take over and Iā€™d again think of my better thought.

Is there any better way to stop the negative thoughts bombarding me?
