When I came in from work tonight she was nearly comatose. Had to watch her for a while to see if she was breathing. There had been no more vomiting. I have no idea how old she is. I've had her for almost four years and my daughter seemed to think she was old when I got her. I don't think this is parasitic. It may just be her time. I might add nothing has changed in my feeding routine. Also, no new snakes have been introduced in nearly a year.
One thing out of the ordinary. When she went after her first pinkie she missed and bit herself not once but twice. That had never happened before. I noticed she had a very small amount of blood on her lip but I couldn't see a mark where she had bit herself. She went on to eat a good meal.
Thanks for everyone's advice.
