Cellular Paranoia

When a person feels like everyone decided to hate them all at once because no matter who they call or text, no one will respond. Generally this is followed by the person calling every single contact in their phonebook, in order to alleviate the condition. Some will also call others off a different person's phone, to see if they are actually being ignored.

Marry had a horrible case of Cellular Paranoia; she called everyone she knew from a payphone to see if they would answer.
