<human>: Tomorrow is my sister's baby shower. I've been volunteered by my mother to take pics of the event. The kicker: three exes and the woman I'm currently seeing (we've been seeing eachother since August) will be there among the other guests. I wasn't worried up until today, when I'm starting to get extremely anxious about this whole thing...

Two of the exes I've seen since we've broken up, and we're on relatively good terms with. The third and most recent ex-girlfriend I haven't seen/spoken with since we broke up, and it wasn't a very good breakup.

Is this situation a ticking timebomb, or am I going to be okay? Is it normal to be this worried? How can I make my guest more comfortable too, so that way my anxiety doesn't feed into her?

<bot>: I'm going to be at a baby shower with the woman I'm seeing where three exes will be there as well. How do I not freak out?
