I'm 28 and in my M3 year. I started a new rotation this past week, and a found out that a PA who'd be working with my team happens to be my boyfriend's ex. Honestly, we don't really know each other at all, so while I have to admit feeling a little weird about the situation, I didn't think much of it. But there was a group conversation about birthdays recently and our ages came up. She's about a year older than me, but even still, she made a comment about how it must be "so uncomfortable to know that the residents I work under are my age" (or even a little younger in some cases). Being terrible at confrontation and witty comebacks, I just kind of laughed it off and went to the nearest computer to do some pretend notes, because I was actually pretty hurt. I had a medical problem during/after undergrad and so sometimes I do feel a little sad to be older in med school. Like maybe if I'd tried harder to work through my treatments I could have applied sooner, been done sooner, be in residency RIGHT NOW, etc. Anyway, I got control of my negative thoughts when I went home, but throughout this week, this girl has made other comments that can't possibly be chalked up to just pure idiocy. Constantly mentioning to me and fellow classmates that her current boyfriend (my age) is just starting as an anesthesia attending, asking me how I don't already know how to do xyz and seeming to act excessively surprised about it. Today's delightful episode took place following a pimping session she overheard, during which she went on about how embarrassing it must be to not know a protocol that a younger classmate had been able to answer correctly. This was within earshot of my team. I'm a pretty average med student and I already feel dumb enough, without having this added crap to deal with on top of the usual pimping and self-doubt. I'm not sure if this best thing to do would be to confront her directly, to report her (I guess to my clerkship leadership), or to do nothing at all and just suck it up for the next few weeks. It's awkward to make a big deal out of this, and I really don't want people to think I'm picking on a PA, being an arrogant med student, or just plain whining, but at this point, I'm getting concerned about my competency being undermined and my grades being affected. Any advice on a best course of action?
