Not to nitpick but it's interesting you used the word "fragile" to describe a woman when referring to hormones. Are men also more fragile due to the hormone level drop in middle age? I never hear the word "fragile" used to describe them. "Crazy", "Wild", "immature", "reckless"? Yeah.Women have a far more fragile balancing act when it comes to hormones than men. But let us not forget, that when men hit their mid year crisis it is usually because their testostorone which keeps them fit in lots of regards, has finally gotten low enough to make a difference in their lives, and they know it.
That hysteria you describe has been used as an excuse to treat women in as the "weaker vessel" for ages. Women obviously can't make sound decisions due to their hormonal nature, right? I don't want to imply you espouse any of this Doc, don't get me wrong. What concerns me is that a normal biological rhythm is often viewed as something unnatural, when it's the most natural thing in the world. I don't think women are naturally predisposed to going bonkers because their hormonal cycles are more pronounced than men's cycles. As snoozan said, it's all dependent on a number of factors.I'm no biologist, but I bet, that if there is a difference in the craziness between the sexes at this delicate time in life, it has alot to do with Menopause, with weight gain, with hypothyroidism, and of course with social norms too. In some respects, women have been allowed to go crazy, throughout history. If men do it, we go to jail. I think in the past, dildo's were actually used to treat female "hysteria" as they called it then.
If someone grieves for another when a relationship ends or is ending, that's normal if there was much love there. Doesn't make anyone crazy, it makes them human.
