I have a routine colonscopy for next week and am slowly losing the plot. It’s for no reason other than my dad had bowel cancer, I had one about 20 years ago and have now been called back for another. No symptoms and had a negative fit test recently. I was really quite Ill with the prep of the last one. I am absolutely terrified of being so ill again and terrified of what they might find. I know I am overreacting massively but I’m on a slippery slope and can’t seem to get control of it all. Part of me just so wants to ring up and cancel. Just knowing what my dad went through is stopping me.
