'High-functioning' anxiety is deceptive because it produces results. You deliver, organise, anticipate problems, avoid mistakes. From the outside it looks like competence; on the inside it's constant tension. The body stays on alert, the mind never rests, and small errors feel like threats. Many people only notice when the cost shows up: insomnia, irritability, pain, exhaustion, panic. Naming it isn't about labels — it's about listening. A common sign is when rest triggers guilt and silence feels unbearable. Practical steps start small: reduce multitasking, leave margins in your schedule, name catastrophic thoughts, ask for help, and treat self-care as maintenance, not a reward. You don't need to break down to deserve support.
