Ya it wasn't Kate, she was the only one who held the character togeather. I think in an interview she said because of the chaotic writing of her character she basically started to portrey her as someone with ptsd, you can see this especially in the episode where they pass through darkspace, and she goes kind of crazy because she is let alone with her thoughts with no crisis to occupy her. That's the one reason Janeway ended up making since as a character, she was deeply messed up.
