There are some stories you don’t want to write. This is one of them.

Mabel Lowe, 17, posted to Instagram on Saturday with a message no older sister should ever have to write. “I love you so much, Fiona ❤️,” she wrote, alongside photos of her younger sister. “I wish your short time here was easier, and I hope your mind is at ease now.”

Fiona Lowe died by suicide on September 29. She was 13 years old.

When a Family’s Grief Becomes Public

Look, I’m not going to pretend I know what it’s like to be Chad Lowe’s kid. The guy’s been in Hollywood for decades – younger brother of Rob Lowe, Emmy winner for “Life Goes On,” you’ve seen him in something even if you don’t remember what. But here’s the thing about being a celebrity’s child in 2026: your grief doesn’t get to be private. Not really.

Mabel’s post was brief. Painfully so. “I will honor you forever and keep your memory alive,” she wrote. “I love you, I hope you knew just how much.” That last line – God, that last line. The uncertainty in it. The regret. Anyone who’s lost someone suddenly knows that feeling, that desperate wish that they knew, really knew, how much they mattered.

Chad Lowe and his wife Kim Painter announced Fiona’s death on September 29. The L.A. medical examiner confirmed she was pronounced dead at 1:14 a.m. that Tuesday. The couple has three daughters total – Mabel, Fiona, and 10-year-old Nixie, who now has to grow up in the shadow of this. In the days that followed, a youth club's heartbreaking tribute gave Fiona's community a way to grieve alongside the family.

The Thing Nobody Wants to Talk About

Thirteen. She was thirteen years old.

And I know we’re supposed to focus on awareness and resources and all of that – and we will, we should – but can we just sit with how young that is for a second? Eighth grade, maybe ninth. Still shopping in the juniors section. Still figuring out who the hell you are.

The rates of youth suicide have been climbing for years now, and it’s not like we don’t know why. Social media pressure, academic stress, the pandemic’s lingering effects on mental health, the general state of… everything. Kids today are dealing with things that would’ve broken most of us at that age. Hell, things that break plenty of adults now.

But knowing the statistics doesn’t make it less shocking when it’s someone’s actual kid. Someone’s little sister.

What Mabel’s Words Tell Us

“I wish your short time here was easier.” There’s a lifetime of helplessness in that sentence. It suggests Mabel knew Fiona was struggling. That the family probably knew. And here’s the brutal truth nobody wants to say out loud: sometimes knowing isn’t enough. Sometimes every intervention and therapy session and heart-to-heart talk still isn’t enough.

“I will honor you forever and keep your memory alive. I love you, I hope you knew just how much.”

That hope – “I hope you knew” – is going to haunt Mabel for a long time. Maybe forever. Because when you lose someone to suicide, you don’t just grieve the person. You grieve every conversation you didn’t have, every “I love you” you didn’t say enough, every sign you think maybe you missed. Even when you did everything right. Even when there was nothing more you could’ve done.

The Impossible Position of Being the Surviving Sibling

I keep thinking about what it must be like to be Mabel right now. Seventeen years old, mourning her sister, and doing it on Instagram because that’s just… what you do now? The performative aspect of grief in the digital age is so weird and uncomfortable, but also – I don’t know. Maybe it helps. Maybe putting it out there, making it real in that public way, is part of how you process the impossible.

And she’s got a 10-year-old sister watching how she handles this. Learning how to grieve by example. That’s a lot of pressure for a teenager who’s barely holding it together herself.

What We’re Not Saying

Here’s what bothers me about how we talk about youth suicide – we’ve gotten so careful, so focused on “raising awareness” and providing crisis line numbers (which, yes, absolutely do that), that we’ve kind of lost the ability to be angry about it. To say this is unacceptable. That losing 13-year-olds should enrage us into actually changing things.

Mental health resources for teens are still woefully inadequate in most places. School counselors are overwhelmed. Therapy is expensive and hard to access. We’ve normalized a level of stress and anxiety in young people that would’ve been considered pathological a generation ago. And we wonder why kids are breaking.

The Lowe family probably had access to resources most families don’t. Money for treatment, connections, privacy. And it still wasn’t enough. What does that tell you about the kids who don’t have those advantages?

There’s No Good Way to End This

I’m not going to wrap this up with some inspiring message about hope or healing or finding meaning in tragedy. There isn’t any meaning here. A 13-year-old girl is dead, and her family is shattered, and no amount of “awareness” changes that.

What I will say is this: if you’re struggling, if you’re reading this and relating to what Fiona must have been feeling – please, talk to someone. And if someone you love seems like they’re drowning, don’t wait for them to ask for help. Most people who are really, truly struggling won’t ask. They’ll just quietly slip under.

Mabel ended her post with “I hope you knew just how much.” Don’t let the people you love wonder. Tell them. Today, not someday.
