The answer is paranoid. Being paranoid is known to be a type of personality disorder, wherein an individual is continuously doubtful and cautious on other individuals, such as friends or even family members, but this characteristic of being paranoid is not considered to be in the high degree of psychotic. People who are easily paranoid are also seen signs of jealousness and are excessively troubled with hidden motives of other individuals, whether towards one’s self or to other individuals, they are seemingly also quick to take offense, especially when they are suspected for any accused action towards them.
