If someone you love is going through this transition, you've probably noticed changes, and you've probably also felt unsure what's actually helpful to do about it. Start by understanding what's actually happening: this isn't 'just moodiness' or something to wait out. Real hormonal shifts are driving physical and emotional changes that can be genuinely disorienting for the person experiencing them. A little understanding of what's biologically happening goes a long way toward not taking symptoms personally. What tends to actually help: believe what she's telling you even if you can't see it (hot flashes, brain fog, and sleep disruption aren't visible the way a cold is), ask what's useful instead of assuming (some days that's practical help, other days it's just not being asked 'are you okay?' for the fifth time), adjust the shared environment without making it a whole conversation (a fan, a cooler bedroom, flexibility on a rough day), and don't take mood changes personally. What doesn't help: jokes about 'the change' even affectionate ones, minimizing ('it can't be that bad'), and trying to fix everything yourself with unsolicited research and solutions. The simplest thing you can do: ask her directly, 'What would actually be helpful right now?' and just listen to the answer.
