1 in 2 teen girls say they rarely feel well-rested — and more than half report persistent sadness or hopelessness.
Our national survey of over 1,000 teenage girls revealed just how widespread the mental health crisis has become. Sleep struggles, body image concerns, academic stress, and social pressures aren’t isolated issues — they’re everyday realities. These numbers aren’t just data points; they represent real girls carrying invisible burdens.
Her Mind Matters exists to ensure teen girls’ voices are heard, struggles are validated, and paths toward healing are supported.
Teen girls are facing a crisis that isn't showing up on the surface.
64% of girls nationally said they feel overwhelmed by stress or anxiety every single day. Nearly half, 48.6%, reported recent thoughts of self-harm. And 31.5% said they have no one to talk to.
Think about that last number for a second. Almost 1 in 3 girls is carrying this alone.
The happiness data is just as stark. Nationally, only 1 in 8 girls feels truly happy with her life. In Aspen, a town most people would assume is doing fine, it's 1 in 17.
These aren't numbers from a distant study. Hallie collected them herself, from real girls who answered honestly because they knew nobody was judging them.
National
vs.
Aspen
The Aspen comparison matters because it shows this isn't just a poverty issue or an urban issue. In one of the wealthiest, most scenic places in the country, girls are struggling just as much, and in some ways more. 73.5% of Aspen girls reported daily stress compared to 64% nationally. Aspen teens also report 20% higher levels of social media-induced stress than their peers across the country.
What's different in Aspen: Fewer girls report having no one to talk to (13.3% vs. 31.5% nationally), and fewer report not feeling physically healthy (8.4% vs. 44.6% nationally). That gap suggests access and community matter a lot.
These statistics are why this project exists.
