Yeah, I might be a bit preoccupied

I told my coworkers I'd be out for a week in July because of nose surgery. In talking about the 6 day recovery estimate, I note that I'm going to be miserable. My quasi-nemesis coworker (the one who works 2x harder than a full time at part time and expects the rest of us to be just as driven and perfectionist...)
She says, "What? From that kind of surgery? Well, with an attiude like that, I guess you will be then."
...
sigh.
( discussion of surgeries and feels. )

So, yes. It might not be so bad. Great! Then I can be pleasantly surprised (which is the only "come back" I had in the heat of the moment). Someday, I'd really like to find a way to tell her that when she says things like that It's hard not to feel like she's dismissing my anxiety and feelings in general. That I should magically just not feel that way.  I am ready to move on from this job. So very much.
