When You're Running on Empty: What Sleep Deprivation Really Does to You (And What Finally Changed Things for Me)

There's a version of me from about six months ago that I barely recognize.

She was snapping at her husband over nothing. Crying more frequently than normal. Going through the motions of motherhood and often feeling disconnected from the joy she thought she'd feel. She was a therapist — someone who literally talks to clients about the importance of self-care and sleep — and she could not pull herself together.

That version of me wasn't broken. She was just profoundly, desperately sleep deprived.

What Sleep Deprivation Actually Does to Your Brain (And Your Relationships)

I've always known, clinically, that sleep matters. I've said it in sessions more times than I can count. But nothing prepares you for understanding it in your body — until you're waking up every one to two hours for six weeks straight with a baby who will only settle for you.

Here's what was actually happening to me, and what happens to anyone operating on fragmented sleep:

Your emotional regulation goes first. The prefrontal cortex — the part of your brain responsible for rational thinking, perspective, and impulse control — is extraordinarily sensitive to sleep loss. When it's impaired, your amygdala (your threat-response center) takes over. You're not overreacting. Your brain is literally running in survival mode. That's why small things feel enormous. That's why I was snapping at the people I love most.

Then comes the disconnection. Sleep deprivation doesn't just make you tired — it blunts your ability to feel present. You can be in the room and not really be there. For me, this was the most painful part. I wanted so badly to soak in early motherhood, and, at times, I felt like I was watching it through glass.

And the cognitive fog is real. Memory, decision-making, creativity — all take a hit. As an entrepreneur and a therapist, I noticed I couldn't think clearly, couldn't access the version of myself I knew was in there somewhere.

The Fear That Almost Kept Me Stuck

When our pediatrician told us our options — keep doing what we were doing, or look into sleep training — my heart dropped. I had already decided, before doing a single minute of research, that sleep training was not something I was willing to do.

I assumed it would damage my daughter's attachment to me. I pictured her crying alone, feeling abandoned, learning that her needs didn't matter. I wasn't going to do that to her, no matter how exhausted I was.

But here's the thing about assumptions: they feel like convictions until you actually look at the evidence.

When we started researching, I was genuinely surprised by what I found. Studies consistently show that sleep training does not harm the attachment between a mother and her baby. In fact, many researchers find the opposite — that when both mom and baby are getting consolidated sleep, the quality of their relationship improves. A rested mother is a more present mother. A rested baby is a happier baby.

We chose the Taking Cara Babies course, and I still remember crying watching the first few videos — not from sadness, but from the overwhelming relief of feeling seen. Cara put words to exactly what I had been experiencing.

What Changed When We Committed to It

The first few nights were hard. I won't sugarcoat that. So we came back to our why every time it got difficult: I needed to be a whole person again, and my daughter needed a mother who was actually present — not just physically in the room.

We completed the full month of training.

Months later, our daughter is a great sleeper. And I am so deeply, genuinely grateful.

She laughs so much now. We play hard together. I feel things again — the good things, the tender things — instead of moving through the day in a fog. My relationship with my husband has improved. It feels like we're right back on track to deepening our relationship each day. My capacity to be patient, curious, and kind has come back online. I'm myself again.

And my daughter? She still loves me. Our attachment is completely intact. My fear was a story I had told myself without any evidence to back it up.

Practical Takeaways if You're Running on Empty

1. Name what's happening. Sleep deprivation is a physiological state, not a character flaw. If you're irritable, disconnected, or struggling — your brain is doing exactly what a sleep-deprived brain does. Practice self-compassion by shifting the story you're telling yourself. Instead of "I'm the worst" or "This is just who I am," try "I'm not getting enough sleep and it's affecting how I show up" or "This is a real hardship, and it makes sense that I'm struggling."

2. Question your assumptions before they make decisions for you. I almost stayed stuck in an impossible situation because of a belief I had never actually investigated. Whatever you've decided isn't an option — is that based on evidence, or fear?

3. Protect sleep like the non-negotiable it is. Whether you're a new mom, a new dad, a busy entrepreneur, or simply a human — sleep isn't a luxury you earn when everything else is done. It's the foundation that makes everything else possible. [link to: self-care/burnout digital product]

4. Ask for help before you hit a wall. Our pediatrician, a course, a supportive partner — none of it could help until I was willing to admit I was struggling. You don't get a prize for white-knuckling it alone.

You Don't Have to Earn Rest

If you're in a season of depletion right now — whether it's a sleepless newborn phase, a business in crunch mode, or just life piling on — I want you to hear this from someone who has been there and also happens to study this stuff for a living:

Sleep is not indulgent. Rest is not weakness. Taking care of yourself is the most important thing you can do for every relationship and responsibility in your life.
