She is screaming in a passion

[LYDIA1997]

The following text is from Agnes Grey by Anne Brontë. What does "In a passion" mean here?

Often these dreadful cries would bring Mrs. Bloomfield up to inquire what was the matter?
‘Mary Ann is a naughty girl, ma’am.’
‘But what are these shocking screams?’
‘She is screaming in a passion.’​

It means something like "a distraught emotional state."

Thank you very much.

I'd say it means "in a temper" or "in a fit of anger". Here's the relevant OED definition of 'passion':
7b. A fit of temper; an outburst of anger or rage. Esp. in to fly (also fall) into a passion. in a passion: violently angry.

I don't think it's used much with that meaning today.
