Should I use 就 in when translating "when you say it like that, I feel confused", e.g. ...我就感到困惑? If I want to say "When you say it like that, I feel confused" would it be "你这么说的时候，我就感到困惑"? Also, if I just wanted to say "saying it like that makes me confused" would that be "这么说让我感到困惑"? Trying to get a feel for how sentences are constructed. Thanks.
In short:

你这么说的时候，我就感到困惑.
Whenever you say it like that, I feel confused.

你这么说的时候，我(会)感到困惑.
When you say it like that, I feel confused.
