Anxiety involves a pattern of threat anticipation: your mind or body prepares for something that feels uncertain, unsafe or difficult to manage. In neurodivergent adults, anxiety can also interact with sensory overload, executive-function demands, social processing, rejection sensitivity, masking and difficulty tolerating uncertainty.
