Hormones change how feelings are presented and what stimuli produce what feelings. I'm on estrogen now, and things that used to cause me to shut myself away and enter a depressive spiral now cause me to just cry, which I suppose is healthier and much much less likely to result in self-harm. It seems likely that the spiraling you have heard of is just another possible result of people's brains expressing existing things differently after a pretty major change in their life.
