Anxiety is not just a feeling that fades for many young people. In the US, 3.4% of children reported anxiety affected daily activities “some or a lot,” while a UK picture shows how need can exist without getting help, with 10% of children who had self-reported mental health needs listing anxiety as their primary concern. As we connect prevalence, onset age, treatment gaps, and the outcomes of CBT, you will see why childhood anxiety is both common and often underestimated.
