The stress and anxiety is real. One year after my diagnosis and treatment I went for my mammogram and ultrasound. Logically I knew after all that treatment it would be ok but my anxiety was off the chart. During my ultrasound I cried. Actually I wept. When I left the ultrasound room I was ok.
With all that anxiety it is helpful to put some strategies in place like walking or other exercise, meditation is amazing and really helps but there is also yoga and mindfulness. Even taking slow deep breaths helps. You could also see a counsellor to help too. They really are helpful and probably could give you other strategies to get through all this.
I hope you are ok @Cora and I hope your results are ok too. Do you have someone to go with you to your appointments? That is a good thing to do as when you are anxious it hard to concentrate. Let us know how you get on if you like. Thinking of you today š. Take care
