Please need some helpful answers for my sister, she’s very ill and I’m worry about what’s going on she’s in the hospital rn ?

My sister is 10 years old, she’s been dealing with violent vomiting on and off for years when she gets a virus. Now today my sister has not been feeling good since last night this morning she started throwing up my parents called the ambulance and she’s at the hospital but they cant stop the vomiting still. They did a x-ray it shows she has micro tearing and the doctors and nurses are scared because she also has a uti and abdominal infection. Their scared that the bacteria can travel and cause sepsis. Their giving her antibiotics to prevent any of that! Now I read about sepsis survivors and all these scary things I just want to know from what I type does it seem my sister will be ok? I feel like passing out I feel dead please need some helpful answers
