You will never find a patient of anything other than brain that will understand you, even if they whole heartedly try. Heart surgery patient will understand your fear of the surgery and its risks, but even they can’t grasp brain surgery. Our brains are the source of our identity, and there is nothing more scary than facing a threat to who we are, and the potential loss of full control over our whole selves. Your sister may struggle with her knees, but she is undoubtedly still identifies as the same person she was before her surgery. Someone poking in your brain is an entirely different fear level. Allow those around you to try to reassure you, but never feel as if you don’t have the right to feel whatever you are feeling regardless of what they say. Rely on friends and family to try to support you as best they can, but come here for understanding. YOU’VE GOT THIS!!
