Children rarely say "I have anxiety". They say their stomach hurts in the morning, that they don't want to go to school, that they can't sleep alone. In teenagers the signal is often an abrupt change: grades collapsing, friends disappearing, a permanently closed door.
Common reasons: separation anxiety, school refusal, bullying, grief, parental divorce, or a transition into adolescence that went badly. In teenagers, social anxiety, body image and — increasingly — the relationship with screens are added.
A group specific to Moldova: children raised by grandparents, with one or both parents abroad. Their distress is real and often silent — the good children, the ones who cause no trouble, are exactly the ones who reach help late.
You don't need a diagnosis to book. If something has changed and it has lasted more than a month, it's worth an assessment.
