I Survived
My advice: if you're like me and terrified of even stepping into a dentist's office, and then proceed to shake like a leaf and cry like a baby during even routine fillings, opt for a sedative if they tell you need a root canal. It worked wonders. I was mellow. Jaw is starting to hurt a bit now, but I'm cool with that.
Go for the sedatives!
