how fucking stupid can you get?
'oh buts shes so brave!, She's so mature for her age!' No she bloody isn't.
She said she's scared of the risks that come with surgery. Sorry but if she doesn't take the surgery she has a 100% risk of dying within the next year.
With the surgery she has a 76% percent chance of seeing her 23rd birthday. She's not going to die in a hospital bed. Hardly anyone dies, in theater, these days during a transplantation operation. She'll be monitored for a bit then allowed home. Where if the transplant fails (highly unlikely) she can go die in her own bed.
Every surgery contains the risk of dying, she obviously heard the 'risks' of this surgery and freaked out a bit. She's probably filled with false hope that since she feels fine a little hole in her heart won't kill her. She's wrong, it will and she needs to man up and have the fucking surgery.
