I have a phobia... (and questions)

I seem to have a phobia of the dentist!
As pathetic as it sounds, I went to the dentist today expecting a check up and found out I had to have a filling.
I am 16 and I started crying.
Pathetic = me!
But she was treating me like a child. And when I was gagging on some of the filling stuff that fell to the back of my throat she pushed me back into the seat and told me (not nicely) that there was nothing that I could choke on. I'm pretty sure there was something there since I had to stop myself breathing so I didn't throw up all over her.
I wish I had thrown up on her. That would have been sweeet!
So, she was a bitch and I have to go back to get another one done!
Maybe this time I will throw up on her!
