"She looks like anything but that" means what?
Capture from a novel..." It doesn't sound like her family likes her much. It sounds like they have reason not to. She lied to them too, and ripped them all off. She doesn't seem like it, but she's a sick woman. She looks like anything but that"

Question

Answer

To be " anything but" means to be the complete opposite.

Person 1: How did she look? I heard she looks like she's fine.
Person 2: she looks anything but fine.  She's sick.

Answer

She likes anything but [not like a sick woman].

The 'sick' he means is not physical. It means she is deceitful, untrustworthy, bad, due to mental defect. So he means that she does not look like a bad, her looks are deceiving. Maybe she acts terribly but looks pretty and nice!
