Matt Sturniolo’s memoir What Happened Yesterday is a grounded, vulnerable look at panic attacks, grief, and the strange pressure of blowing up on YouTube before you have figured out how to operate in the real world.
Written by one-third of the ultra-popular Sturniolo Triplets, What Happened Yesterday is a quick, 242-page memoir about growing up with severe anxiety in the public eye. It skips the preachy self-help lecture and focuses on real, messier realities: panic attacks, house fires, losing a family member, and trying to function in everyday situations. It lands best for middle schoolers and high schoolers who already watch the triplets or want a candid look at mental health.

If your tween or teen spends any time on YouTube, you have probably heard the Sturniolo Triplets yelling over fast food in a parked minivan. Matt, along with his brothers Chris and Nick, built a massive internet following on rapid-fire banter, chaotic energy, and relentless uploads. On camera, Matt often plays the quieter, sarcasm-leaning brother.
In What Happened Yesterday, he steps out of the group dynamic to explain what was actually happening when the cameras turned off. The book digs into his history with crippling panic attacks, confusing therapy sessions, and major family hardships—including a house fire that wiped out his childhood home and the loss of his grandfather.
Matt unpacks those moments with dark humor and plain language. For kids who only see the polished, high-energy clips on their feeds, reading about his actual internal daily struggle offers a reality check on creator culture.
Most influencer books fall into one of two traps: a ghostwritten cash-grab full of backstage gossip, or a glossy lecture on "how I made it." Matt avoids both by keeping the scope personal.
The core idea comes from advice his mom gave him growing up: yesterday’s problems shouldn't affect today. Instead of promising a dramatic, magical fix for anxiety, the book celebrates unglamorous, everyday victories:
- Making it through a full day of school without running out the door.
- Standing alone in a grocery store checkout line during a spike in heart rate.
- Getting behind the wheel to learn how to drive when panic says to stay home.
That framing matters for young readers. It treats mental health as an ongoing process of small adjustments rather than a problem you solve once and forget about.
If you are deciding whether to hand this to a middle schooler or teen, here is how the content breaks down:
- Age Range: Ages 12 and up. Middle schoolers and high schoolers who already follow the Sturniolo Triplets will burn through it in a single afternoon.
- Content Concerns: The book deals directly with anxiety, panic attacks, therapy, physical distress, grief, and emotional burnout. There is light language and some dark humor, but nothing graphic or gratuitous.
- Reading Level: Highly accessible. Written in Matt’s natural speaking style, the 242 pages move quickly with short chapters and straightforward prose.
If your kid usually resists reading print books but spends hours watching YouTube creators, this is an easy win. It uses their existing interest in creator culture to get them engaging with a physical book about emotional resilience.
If your kid reads the book, these questions open up quick, pressure-free discussions:
- On screen vs. reality: "Matt talks about filming funny videos while having a terrible panic attack off-camera. Why do you think people on social media hide that stuff?"
- On small wins: "He counts making it through a grocery store line as a big victory. What is a small daily thing that feels harder than it looks to other people?"
- On reset buttons: "His mom told him that yesterday's problems shouldn't affect today. What helps you reset when a day starts out rough?"
The biggest hurdle for kids dealing with anxiety is feeling like everyone else has things figured out. Creator memoirs like this work because kids already trust the voice—they have watched Matt in hundreds of videos. When an influencer they follow drops the confident persona to talk plainly about panic attacks and therapy, it removes the shame around those topics faster than any lecture from an adult.
