How should I stop having anxiety when being home alone? Whenever I am home alone, I get scared that everyone else on earth disappeared, and that I am the only person left. Even when people are home, every hour I just look outside my room for someone, and if they aren’t where they usually are I panic and run around the house. When I finally see someone my anxiety subsided and I become fine again. I have no clue why this is the case, and why my brain thinks everyone will disappear. How can I fix this?
