Waiting to find out is hard - how do you carry on with life as ''normal''?

Hi, I'm waiting for an endoscopy & biopsy as my GP strongly suspects throat cancer. My poor fiancé is beside himself but staying strong for me. I have a week to go before my appointment, but how do you carry on with life as "normal" when there's that fear hanging over your head that it may be the big C? ️️
