How do you cope with extreme anxiety before open-heart surgery?

I am preparing for open-heart surgery and I am experiencing a high level of anxiety, so I would like to understand how to cope with extreme anxiety before the procedure.

Open-heart surgery can feel really frightening, and it’s completely normal to feel overwhelmed. My grandfather went through the same thing—he was extremely anxious beforehand. But hearing positive recovery stories and having honest conversations with his surgeon gradually helped him feel more at ease and confident going into the surgery.
