Hello,my friend has been experiencing symptoms of coughing up blood and she's finding it very stressful and won't go to the hospital,is there any advice on what it could be and what to do?

Put her in the car and drive her to the hospital, how old is this friend,

I have tried making her phone an ambulance,and she is 17 year old

There is no help we can give on the internet. She needs a hospital. Where are her parents?
