When the child is convinced that everything and everyone in the world is potentially dangerous he or she is experiencing?

The child is experiencing hyperarousal or hypervigilance, which are common symptoms of severe anxiety or post-traumatic stress disorder (PTSD). This heightened state of alertness can interfere with the child's ability to feel safe and secure in their environment, leading to difficulty in forming trusting relationships with others. Therapy and support can help the child learn to manage their anxiety and feel more secure in the world.
