Worst-Case Scenario

I went to the dentist today as my condition was not improving very much. As I sat in the chair that forced me into a reclined position and waited for the doctor, the grinding from another room filled me with unease. They had already taken my x-ray. Now I was just waiting to hear. I was thinking a sinus infection, gum infection treated with some antibiotics, worst case scenario they cut me and clean the infection. I could handle this, going in, knowing what to expect. I had prepared myself for this. This however is not what I got.
The dentist very bluntly let me know that I had a cyst in my mouth, that possibly developed over years from an earlier dental incident. I needed to go to a specialist for oral surgery to remove it, then possibly a root canal, and there was a small chance of losing one of my front teeth because of possible nerve or bone damage. OK, I am not an easy queesy but anything involving my teeth, I just cannot handle. I have had nightmares for years of my teeth falling out. Now you're telling me this nightmare might come true? Suddenly I got shaky and panicky, though I tried to maintain composure in the office. Once I got out I was a mess, pacing the sidewalk, holding my mouth, hot flashes of panic and dread. It was like being thrown in a box filled with whatever makes you feel the most icky.
The surgery is set for 12 noon tomorrow. I made the appointment while still in the other office, I just want this shit taken care of!! Honestly, I am scared shitless. I am just trying to hope that the situation is better than I fear. You might think this an absurb fear, but to me it's quite real. at any rate, I'll keep you updated.
