go bananas

Would you tell me whether I am right with my interpretation of the expression in bold in the following sentence?

Liza moved into the sheltered regimental Barbizon Hotel for Women. Liza sais: “I went bananas!”.

go bananas = go mad

Thanks for your efforts.

Not really mad, but very excitedly confused or depressed.

Hi MM,

Thank you for your further explanation.
