3. paranoid?!?
“is a mental disorder characterized by paranoia and
a pervasive, long-standing suspiciousness and
generalized mistrust of others. Individuals with
this personality disorder may be hypersensitive,
easily feel slighted, and habitually relate to the
world by vigilant scanning of the environment for
clues or suggestions that may validate their fears
or biases. Paranoid individuals are eager
observers. They think they are in danger and look
for signs and threats of that danger, potentially
not appreciating other evidence.”
