WORKBOOKS & TOOLKITS
FOR SINGLE MOTHERS BY CHOICE
Choosing motherhood does not mean choosing to do everything alone.
A workbook on loneliness, connection, and care for single mothers by choice, with reflections, practical tools, and space to work through what support could look like for you.
Choosing motherhood does not mean choosing to do everything alone.
How are loneliness and isolation showing up for you as a single mother by choice?
Written by a therapist who is also a single mother by choice, this workbook makes room for both truths: loving the family you chose and needing more support than you have.
Inside, you’ll find plain-language tools drawn from CBT, ACT, DBT, and parts work, worksheets with real writing space, and reflections on being the only adult at home, feeling misunderstood even in single-mother-by-choice communities, asking for help that actually helps, and setting boundaries when you depend on the person helping you.
For anyone considering single motherhood by choice, trying to conceive, pregnant, postpartum, or parenting.

ABOUT BETH
I’m a single mother by choice, a former early childhood educator, and a therapist who believes in zooming out to see the full picture.
My clinical work, lived experience, and background in expressive arts shape how I listen, write, and teach. I pay attention to what gets overlooked, whose experiences are left out, and how our words can make room for greater understanding and connection.
From My Writing
Reflections on motherhood, identity, grief, relationships, and the in-between.
MOTHERHOOD
I Sometimes Feel Like Screaming
What happens when postpartum overwhelm, sleep deprivation, resentment, and the pressure to keep functioning have nowhere to go? A look at mom rage, what can live underneath it, and why admitting it matters. READ →
FAMILY BUILDING
It’s the Act, Not the Narrative
Donor conception is often discussed through the story we tell about it. I found myself thinking about something more fundamental: what actually makes an act of creating a child intimate, meaningful, or ours? READ →
GRIEF + TRANSITION
The Death, Birth, and Rebirth Sandwich
After becoming a mother, early postpartum felt strangely familiar. I eventually realized why: so much of it reminded me of sitting shiva for my father, and of the rituals humans have long created to carry us through the experiences that divide life into before and after. READ →
