Banana
I spoke with a psychologist years ago who asked me to tell myself something crazy whenever I had an unwanted or negative thought enter my head. Instead of fighting to get rid of the thought, I would say: 'YEAH, right, I'm a banana.' I put a sticky note with a drawing of a banana on it that said IM A BANANA on my fridge. My kids came home from school and killed themselves laughing at this. They called me Banana Mum for about 6 months. At first, I was embarrassed, but afterwards, it made the cognitive diffusion work even better. I'm going to start using the bananas reference again. It still makes me laugh to think of the kids giggling and chanting 'I'm a banana' whenever any one of us said something stupid. I believe this is going to work. I quite liked being banana mum and maybe 20 years on, I can feel that light-hearted again.
