It’s been over a decade since we first met Rae Earl on E4, and honestly, the impact of season 3 My Mad Fat Diary hasn't faded one bit. For those of us who grew up feeling like a perpetual outsider—too loud, too big, or just too much—this show wasn't just TV. It was a lifeline. But then came the final season. It was short. It was brutal. It felt like a punch to the gut after the relatively hopeful vibes of the second year.
Most teen dramas treat recovery like a linear mountain climb where you eventually reach the top and stay there. Season 3 My Mad Fat Diary took that trope and set it on fire. It showed us that "better" isn't a destination; it's a messy, recurring choice. If you’re revisiting it now, or maybe watching it for the first time in 2026, you’re probably noticing how raw it feels compared to the polished, TikTok-ready mental health "aesthetic" we see today.
The Bittersweet Reality of Moving On
University applications. Driving tests. The terrifying realization that the "Gang" isn't a permanent safety net. This is where the season starts, and it’s deeply uncomfortable. We spent two seasons falling in love with Chloe, Chop, Izzy, and Archie, only for the final three episodes to tell us that growing up means leaving them behind.
It sucks.
But it’s real.
The core conflict of the season isn't just Rae’s body image or her relationship with Finn; it's the paralyzing fear of the future. When Rae starts spiraling again, it’s not because she’s "weak." It’s because the stakes have changed. In the first season, she was just trying to survive the day without her secret getting out. By the time we get to season 3 My Mad Fat Diary, she’s trying to figure out who she is without the labels she’s used as armor for years.
Sharon Rooney’s performance here is nothing short of a masterclass. You can see the exhaustion in her eyes. The way she tries to "perform" being okay for Finn while slowly drowning under the weight of her own expectations is something that hits hard for anyone who has ever suffered from high-functioning anxiety or depression.

Why the Short Length Actually Worked
A lot of fans were (and still are) annoyed that the final season was only three episodes long. People wanted a full ten-episode arc with a wedding and a happy ending for everyone. Honestly? That would have ruined it.
The brevity of the final chapter mirrors the frantic, claustrophobic feeling of the end of teenage years. Everything happens too fast. One minute you’re eating chips at the pub, the next you’re packing a car and saying goodbye to the only people who ever truly saw you. By keeping the season tight, the writers forced us to sit with the discomfort of Rae’s relapse and her eventual, hard-won breakthrough.
The car crash sequence—without giving away every beat for the uninitiated—is a literal and metaphorical turning point. It’s the moment where the show stops being about "teen problems" and starts being about the adult reality of consequence. Rae has to realize that her self-destruction doesn't just hurt her; it ripples out.
The Finn Nelson Problem
We have to talk about Finn. Nico Mirallegro turned Finn into the ultimate "indie dream boy," but season 3 My Mad Fat Diary subverts that perfectly. For a while, we all wanted Finn to be the "cure" for Rae. We wanted his love to be the thing that finally made her feel thin, pretty, and worthy.
The show’s refusal to let that happen is its greatest strength.
Finn is incredible, but he’s also just a guy. He can’t fix her. In fact, the season shows that being in a relationship while your mental health is in the toilet is incredibly difficult. It requires a level of honesty that Rae isn't ready for at the start of the season. Watching them navigate the "long-distance" conversation is a rite of passage for anyone who has ever tried to hold onto a first love while their lives are moving in opposite directions.

Mental Health Representation That Doesn’t Lie
Most shows today use "trigger warnings" as a formality. Season 3 My Mad Fat Diary is inherently triggering because it doesn't look away from the ugly parts of self-harm and disordered eating. It shows the relapse. It shows the hospital bed. It shows the terrifying moment when you realize you’ve let everyone down again.
But it also shows Dr. Kester.
Ian Hart’s portrayal of Kester is the anchor of the series. The sessions in the final episodes are some of the best-written scenes in television history. There is no magic pill. There is no "aha!" moment where everything becomes easy. There is only the realization that Rae is the one who has to choose to live. The diary isn't just a place to vent anymore; it's a record of her survival.
Real experts in adolescent psychology often point to this show as a gold standard because it avoids the "glamorization" of the struggle. It looks messy. Rae’s room is a disaster. Her skin isn't perfect. Her hair is greasy when she’s depressed. It’s a far cry from the "sad girl" tropes that dominate social media.
The Legacy of the 90s Setting
The Britpop soundtrack and the lack of smartphones aren't just for nostalgia. They serve a narrative purpose. In the world of season 3 My Mad Fat Diary, Rae can't hide behind a screen. When she’s feeling isolated, she is actually alone. This isolation heightens the emotional stakes.
The 90s setting also highlights the lack of resources available at the time. There was no "Mental Health Awareness Month" in the way we have it now. The stigma was louder, heavier, and more suffocating. Watching Rae navigate that world makes her eventual acceptance of her own brain feel even more heroic.

What You Should Take Away from the Finale
If you’re struggling right now, watching the end of this show can be a double-edged sword. It’s heavy. But the ending—Rae on that train, heading toward a life she built for herself—is one of the most honest depictions of hope ever filmed.
It tells us that you don't have to be "fixed" to move forward. You just have to be willing to take the next step, even if your hands are shaking.
Actionable Insights for Fans and Rewatchers
- Watch the show alongside the real Rae Earl’s books. The TV series is a fictionalized version of her real-life diaries. Reading the source material provides a fascinating look at what was changed for the screen and what remained painfully true.
- Listen to the soundtrack as a time capsule. Music was Rae’s primary coping mechanism. If you find yourself spiraling, creating a "Rae Earl style" playlist of songs that make you feel powerful (think Oasis, Blur, or Pulp) can be a legitimate grounding exercise.
- Acknowledge the relapse. If you are in recovery for anything, don’t view the events of season 3 as a failure. View them as a realistic portrayal of the "two steps forward, one step back" nature of healing.
- Check out the cast’s later work. Seeing Sharon Rooney in massive projects like Barbie or Jodie Comer in Killing Eve is a great reminder of the incredible talent that started in this small, gritty British drama.
- Use the "Kester Method." When you're overwhelmed, ask yourself what Kester would ask Rae: "What is the voice in your head saying, and is that voice actually yours, or is it someone else’s?"
The beauty of season 3 My Mad Fat Diary is that it doesn't give us a "Happily Ever After." It gives us a "Happily Right Now." It reminds us that while the gang might scatter and the boys might leave, the relationship you have with yourself is the one that actually matters. It’s a hard lesson, but it’s the only one worth learning.
If you're looking for more grounded, realistic portrayals of the late 90s UK scene, searching for archives of The Word or early issues of NME from 1996-1998 can provide the cultural context that fueled Rae’s world. Understanding the "Cool Britannia" era helps explain why Rae felt so much pressure to be the "cool, effortless girl" in a world that was anything but effortless for her.
Ultimately, the show remains a masterpiece because it refuses to apologize for being loud, messy, and fat. It demands space. And in the final moments of the series, Rae finally stops asking for permission to exist. She just does.
Next Steps for Your Rewatch:
Find the original broadcast versions if possible. Some streaming platforms have replaced the iconic Britpop tracks with generic library music due to licensing issues. The show loses a significant part of its soul without the specific needle drops of Radiohead and Suede. Searching for the original DVD sets or "original soundtrack" versions is the only way to experience the story as it was intended.
