Stupid Mouth

Good god my mouth tastes bad. I apparently had two cavities and had the one filled today. All I keep smelling is the god awful "drilling of my teeth" smell and it's making me want to vomit. My anxiety is also up and will be so the next few days over developing some kind of infection (I was told by a cardiologist years ago that I had a heart murmur and when the dentist found out, I was required to be checked out by a doctor before I could come back. I had an ultrasound done that ruled out having a murmur, but whether or not I have one, I don't know. But it makes me nervous going to the dentist now). And now I have to do it all over again on Thursday.
