I have started something new that seems to be working. When my brain starts cycling down a path of self-created arguments, I have started telling myself "fake news!" when i realize what I am doing.
Have you ever done the same? Had a thought and then respond to that thought..and before you know it you are so upset about a situation that hasn't even happened!
I was driving in the car the other day and found myself doing that. I was alone so I said outloud... Fake News! It made me laugh but was a way to jolt myself out of that frame of thought.
I'll let you know how it goes as I keep doing it!
