I am sorry to hear about Cutie Pie. How long has she been like this?
My name is Rebecca. I am a veterinarian and will do my best to help.
I am worried about her from your description; she may need medical attention. If you check her gums, are they pink in color? If they look pale, she needs to see a veterinarian.
I see she is not eating, will she at least drink water or broth or any liqiuds? If she is vomiting, and having liquid poop, and not eating, the first concern is that she will become dehydrated and that can make her condition worse. Try to see if she will take broth or Pedialyte or even just water. If she won't drink, or if she drinks but it comes right back up, she needs medical attention.
This could be an infection, or a blockage in her stomach or intestines. You could try Pepcid AC for the vomiting, and/or Pepto Bismal for the watery stool, but if she can't hold these down they won't help her.
Let me know what else I can answer or help with.
