The anxiety from nowhere, the rage over nothing, the 3am wakefulness, the glass of wine that now wrecks you and a doctor who ran one test, said "normal," and offered an antidepressant. Everything you're feeling has a mechanism, it's measurable, and it's far more fixable than you've been told. This is the explanation no one gave you - symptom by symptom, with the actual physiology.

What's Inside

• The reframe that changes everything: perimenopause isn't low hormones, it's the chaos phase - oestrogen and progesterone lurching and crashing for up to a decade, and your nervous system feeling every swing.
• Why your own progesterone is your brain's natural calm (the progesterone → allopregnanolone → GABA story) and why its drop feels like anxiety, inner unrest and waking at 3am.
• Why a single blood test on the wrong day is so misleading - and what to test instead.
• The mechanisms behind the rage, the palpitations, the wine intolerance, the sleeplessness and the brain fog.
• The exact GP bloods to request and the functional hormone testing that actually reveals it, with two tear-out test sheets.
