Freaking out over colonoscopy?

Hi, Renee!
Boy, your anxiety is talking a blue streak! The most common complications are abdominal discomfort and minor bleeding. Very few people have serious complications.
You're looking at a figure of 1/1000 but look at it this way:
"Are these examinations safe? Yes, these examinations are safe, especially when carried out as part of prevention. The risk of complications is very low. The frequency of the appearance of complications during the endoscopy of the upper GI is 0.1%, while during a colonoscopy it is 0.3%."
And remember that those figures reflect all the minor complications as well as anything more serious.
Personally, I've had two colonoscopies and my husband had three plus an endoscopy. They were fast and painless with no complications at all.
This is not to say that no one will have problems but I wonder if the risks of the the conditions you're being tested for aren't riskier than the procedures themselves.
I hope this helps in some small way and I hope your procedures go as smoothly as ours did.
