Yesterday my mom noticed (at a funeral) that I wasn't praying or participating in the mass. She confronted me about it, and I told her that no, I am not Catholic. Apparently it's sinking in and she's a bit hysterical... crying and screaming that she doesn't know me anymore.
What do I do? I don't know how to react/behave when she's doing this. It's like she wants me to feel like I'm doing something wrong, but it isn't working, so she's getting hysterical.
I gave her a hug when she calmed down and told her I love her. That seemed to help, a little. Based on her previous behavior in situations where I've done something "wrong," she will (in the future) make barbs and slight passes at my beliefs. (Already she made one: insisting my love of science is causing my social anxiety disorder.) The advice given in the comments is really helpful. I plan on making the most of it.
