I really need to do a better job of responding calmly to realizing I'm being gaslighted (gaslit?), because my first instict is to scream and break things.

Yes, I do have to go to work tomorrow if it is not closed due to the weather, because I have work to do and I absolutely do not trust my co-workers to not talk about me if I don't show up. No, I am not being unreasonable and I am not actively trying to make you "die of a heart attack from worry". No, bringing up the same topic 50 times today will not make me change my mind or put up with your bullshit.
