Fuck doctors tbh.

My disabled friend (im disabled too) is being a fucking retard.
She was the toastmaster and turned toastmasters into a big blogpost and said that today a doctor told her that she was partly deaf after a surgery she had, but that she ONLY noticed she was part deaf AFTER he told her.
And then after she went back to sit down someone gave a speech, after the speech she went back on the lectern and cried saying she could hear almost nothing during that speech all of a sudden.
After someone I did a speech she went up crying and frantickly pannicking saying that she couldn't hear ANYTHING from my speech (im pretty loud).
It was clear that she was psychogenically magicing herself into believing she cant hear during speeches, she could hear everything else eventho we spoke to her further away.
She has some medical and mental issues so she thinks she can't learn any new skills so she cried about not being able to learn sign language when literal low functioning downsyndrome people know sign language!
She was acting really self pittying saying stuff like "i just carry on anyway!" and making those self pitying gestures.

How do i convince her that her doctor is fucking lying and making her sick with magic?
