If I am alone, my light is on. If a person enters a room my light is still on, but I start feeling anxious. If a person comes close to 90cm distance from me, my light starts dimming and I start to tremble. My anxiety is more intense. If a person comes even closer, my trembling is worse and my light is flickering and dimming more off. If a person comes to 30cm distance from me, I enter panic zone, I tremble even more and lose my light. If a person moves away, my light is back on.
