Last month I was at a bar in Fort Lauderdale.
Spring break crowd was live. Twenty-somethings everywhere.
Every single person around and on spring break was cycling through the same loop. Instagram. Snapchat. TikTok. Back to Instagram. While standing next to their friends, bobbing their heads to the music in real life.
Lonely in a crowd. Craving the next hit.
I've been thinking about that night ever since - not because it was unusual, but because it wasn't. And because of what it implies for where behavioral health demand is actually heading, and whether the platforms being built today are positioned for it.
Trilliant Health published its 2026 Behavioral Health Report two weeks ago. The headline number: behavioral health utilization has increased 62.6% since 2018, reaching 1,346 visits per 1,000 people. Anxiety disorders have grown 89.3%, with the highest utilization concentrated among women ages 18 to 44. Adults 18 to 25 carry the highest prevalence of any mental illness of any age cohort at 33.2%.
The economic burden behind it: untreated mental illness cost the U.S. economy an estimated $477.5 billion in 2024, projected to exceed $1.3 trillion annually by 2040.
That's the demand curve most behavioral health theses are underwriting right now. Strong, defensible, growing.
Here's what most of those theses aren't pricing in yet.
Three Forces That Aren't in Your Model
1. Social media's delayed clinical presentation
The teenagers who grew up on Instagram, Snapchat, and TikTok from age 13 are now 25 to 30 years old. The research on social media and adolescent mental health has been building for a decade. What's less discussed is the lag.
The psychological effects of chronic dopamine dependency, social comparison, and attention fragmentation don't always present clinically in adolescence. They present in early adulthood, when the coping mechanisms run out and the demands of work, relationships, and identity become real.
The bar I was sitting in wasn't full of teenagers. It was full of adults who never learned to be alone with their own thoughts because they never had to be.
