Sounds like a little spiritual crisis. The interesting thing is usually when we cry, we have some inkling about why. How you handled it sounds pretty reasonable given the shakeup you’ve had. Have the people around you been upset with you because of your weepiness? do they support you, and try to wait it out with you? or? I call this kind of experience “being blindsided” by feelings I didn’t see coming. When I have big losses or shocks, this kind of thing can happen. But since you can’t identify what provoked it, I’d suggest waiting a couple of weeks, pay attention, and if you don’t feel pretty much like yourself and haven’t had any insights on your own, have a talk with either a counselor or – anti-religious people don’t get all up in arms here, please – a spiritual advisor. They do exist, they have training and good boundaries; if you want to follow up, pm me.
