Hi Candice,
I am not surprised at your reaction. I had an MRI due to sudden facial drooping almost two yrs ago and they found my aneursyms. To actually realize your own mortality is a hard thing to cope with. I'd find someone to talk to... possibly a friend that has had serious health problems or a therapist. It is really helpful to vent. People near you often feel that you have "been fixed", look fine, and need to move on. It takes time.
