A memoir

Overnight

When the person you love disappears into bipolar disorder.

Same man. Same kitchen. Same coffee cup on the bench. A different person on the inside.

The premise

Nine years of marriage. Seven days of not sleeping, talking faster, a coldness that kept getting colder. Then one morning, with a flatness that still haunts her: I don't love you anymore. This book holds that week under a microscope — because understanding the mechanism is how Diane got back on her feet, and how you will get yours.

Inside the book

01

The anatomy of an overnight
What an episode does to love — the appraisal system, the calm, the box.

02

The first 72 hours, hour by hour
How to keep yourself steady when the ground is still moving.

03

The crash course on bipolar disorder
Bipolar I, Bipolar II, and why it so often gets missed — in plain language.

04

Scripts & reflection prompts
The words to say out loud, and the questions to sit with after.

Seven days

Day 1

He said it on a Tuesday: I can't imagine my life without you.

Day 6

He stood at the kitchen window and said he felt like he was in a box.

Day 7

By the following Tuesday, he could not look at me without something close to hatred.

Excerpt

"The thing that frightened me most was the calm. A decision that should have cost him everything seemed to cost him nothing."

Who this book is for

For everyone holding two truths at once: that the person who left you was real, and that the illness that took them was too. Not a clinical manual — a steady voice from someone who has stood in your kitchen.

If you ever sense your partner is in danger, that concern comes before anything in this book.
