Amy Morin Lost Her Husband at 26. Then She Wrote the Letter That Reached 50 Million People.

Amy Morin is a psychotherapist, the bestselling author of seven books, and the host of the podcast Mentally Stronger with therapist Amy Morin. She currently lives on a boat in the Florida Keys. But none of that is where her story starts.

It starts with a letter she wrote to herself on one of the worst days of her life — a letter she never planned to publish.

On this episode of Success, Rewritten, Amy talks about grief, identity, and what it actually means to be mentally strong. What she shares is not a polished origin story. It's the messy, human version — the version that’s continued to unfold.

The Losses That Launched a Movement

A year into her career as a therapist in rural Maine, Amy's mother died suddenly from a brain aneurysm. She found herself grieving while also working as a grief professional — and quickly discovered that the tools she'd learned in school fell short when the pain was her own.

"A lot of the skills and tools and things that I had learned in college actually fell pretty short when you're going through a painful experience," she says. "They looked good on paper, but in real life — here are these things that I thought were really helpful, but I didn't find them as helpful as I thought they should've been."

Three years to the day her mother died, her 26-year-old husband died of a heart attack.

"To lose the two people in my life that I was closest to in really unexpected and sudden ways did a real number on my brain."

She got three days of standard bereavement leave. When she applied for short-term disability, she was told they don't cover grief. It took her sister (also a therapist) marching her to the doctor to get a diagnosis of acute stress disorder and roughly two months of time off. Then she went back to work — while her own life, as she puts it, was in shambles.

Why "Time Heals Everything" Is a Lie

Amy is direct about this: the cultural messaging around grief isn't just unhelpful. It actively gets in the way of healing.

"Time heals everything is a lie. It heals nothing. If you just sit and wait to feel better, it doesn't work."

The instinct, she explains, is to avoid the pain — to stay busy, to white-knuckle it, to move on. But avoidance isn't healing. The people who walked into her therapy office a decade after a loss, still not feeling better, had often spent those years sidestepping the grief rather than working through it.

She also pushes back on how we support people who are grieving. Asking someone "how are you?" in the middle of their workday, or showing up at a funeral without checking first — these come from good intentions, but they often serve the person doing the checking-in more than the person going through the loss.

"Is this serving my need because I'll feel better when you say you're okay, or is this really helpful for me to ask you during your lunch break how you're doing?"

The Letter She Never Meant to Publish

Years later, after remarrying and finding stability again, Amy faced a third loss: her father-in-law was diagnosed with terminal cancer. On one of her worst days, she sat down and wrote herself a letter.

Not a list of what to do. A list of what not to do.

"The last thing I needed was a list of what to do, so I wrote myself a letter of what not to do. Number one on the list was don't feel sorry for yourself."

She put it on the internet. She got paid $15 for it. She expected five people to read it.

Fifty million people read it.

Media outlets from CNN Mexico to MTV Finland started calling, wanting to speak with "the expert on mental strength." There was just one problem: Amy didn't feel like an expert.

"I didn't write this from the top of the mountain. I'm at the bottom of the valley and I struggle with all of these things."

She decided that if she was going to write the book, she was going to tell the whole truth. 13 Things Mentally Strong People Don't Do came out in 2014, hit the Wall Street Journal and USA Today bestseller lists about a year and a half after publication — driven entirely by word of mouth — and hasn't stopped selling since.

Mental Health and Mental Strength Are Not the Same Thing

This is one of the most important distinctions Amy makes, and one she comes back to in every book and every conversation.

Mental health and mental strength are not the same thing. Having a mental health condition does not make you mentally weak.

"It's kind of like you could go to the gym and work out to become physically strong. If I start lifting some weights, my muscles get bigger, but that doesn't mean I won't ever get a physical health issue. I might still have high cholesterol or high blood pressure despite the fact that I'm working on building physical strength. Mental strength's the same."

Mental strength, she explains, isn't about feeling strong all the time. It isn't reserved for Navy SEALs or elite athletes or people whose lives are currently going well.

"People aren't born mentally strong. It's all about the choices that we make every single day. It's not about feeling strong 100% of the time either. It's just about knowing, what am I gonna do when I don't feel strong?”

That question — what am I going to do when I don't feel strong? — is the foundation of her most recent book, The Mental Strength Playbook.

Running the Play

The Mental Strength Playbook is structured around the idea that mental strength is a strategy, not a state of mind. Each chapter presents a specific "play" — a CBT-grounded tool — and walks through when to use it, why it works, and how to do it.

The format came directly from what Amy was seeing in her therapy practice: clients who had committed to one approach (meditation, mindfulness, journaling) and still felt stuck. Not because those tools were wrong, but because no single tool works for every situation.

"A lot of people assume if I don't feel strong, then I'm not strong, and my argument is you just need to know a play that you can run. You pause, you pick, you run the play."

The book is designed as a reference guide — something you can flip open to the section you need in the moment you need it. At 2pm on a Tuesday when you're about to walk into a meeting and your personal life is currently a dumpster fire.

The Labels That Keep Us Stuck

One of the plays in the book is called "name it to tame it" — the research-backed finding that labeling an emotion actually reduces its intensity. Saying "I'm anxious" helps your brain and body make sense of what's happening.

But there's a difference between labeling an emotion and labeling yourself.

"Sometimes we place labels on ourselves like, 'I'm a really anxious person.' And then guess what? It's that label that keeps us stuck in a lot of ways."

When you identify as an anxious person — or a perfectionist, or an overthinker — the label stops describing a pattern and starts defining your identity. It becomes a self-fulfilling prophecy. It tells you what you can't do before you've tried.

The alternative isn't to pretend the pattern doesn't exist. It's to hold it without becoming it.

"I grew up an incredibly anxious kid, so to this day I'll have anxious thoughts. And I can accept there's a part of me, of my brain that always wants to go to the worst case scenario, and that's okay. I don't have to silence it, but I don't have to listen to it either. Instead, I can be my own boss and say, 'Eh, I'm gonna do this thing anyway.'"

Your Emotions Are Not Good or Bad

Amy challenges the language we use around emotions — including within the field of psychology itself.

Emotions are not positive or negative. They're information.

Anger can give you courage to speak up when you otherwise wouldn't. Excitement can lead smart people into terrible decisions. Anxiety can make you say no to opportunities that have nothing to do with what you're afraid of.

Understanding what you're feeling — and how that feeling might be influencing your decisions — is the difference between reacting and choosing.

Amy describes a simple exercise she uses: giving executives two minutes to write down as many feeling words as they can. The average? Five. Most people get stuck after mad, sad, happy, and scared.

She recommends taping a list of feeling words to your bathroom mirror. Read through it morning and night. Ask yourself how you actually feel — not just "good" or "stressed," but what specifically.

"Until we get to that point where we can even name what we're feeling, we're not there yet."

The Two-Minute Gratitude Flash

One of Amy's most practical plays: set a timer for two minutes and write down everything you're grateful for right now. Not "clean water and air to breathe." Specific things — the coworker who held the door, the car that started fine, the clean shirt you found in the back of the closet.

The timer matters. It creates pressure that keeps the pen moving. And because gratitude memories are stored together in the brain, the more specific things you name, the more your brain surfaces. By the end of two minutes, most people say they feel lighter.

Grateful people, Amy notes, sleep better, live longer, and are about 15% happier. It's an underrated superpower you can use at your desk on a bad day.
