I've got diagnosed general anxiety disorder and also suffer from health anxiety. I have had some abdominal pain under my left ribs that occasionally radiates out, was advised to go see a doctor by our healthcare phone line, the doctor said she's not concerned but to get an ultrasound and go to the hospital if it gets worse, I develop a fever, etc. The doctor said it could even be stress/anxiety causing the pain.

The earliest ultrasound is in a week and I'm incredibly anxious. The pain isn't that bad but I'm hyperfocusing on it and castrophizing in my mind. I feel very panicked and anxious, plus theres the abdominal pain that I'm self checking constantly. 

I can deal with my other types of anxiety fairly well but nothing seems to work with my health anxiety. Any tips?
