Answer:
Delusions of persecution
Explanation:
Delusions of persecution is a set of delusional conditions in which the affected person believes he is always being persecuted.
It is very common in cases of paranoid schizophrenia. There are two central elements that are considered fundamental to characterize the persecution craze. The first of these is when the individual thinks the damage is occurring or will occur. The second is when the individual thinks that the perceived and identified persecutor intends to harm him of any kind, whether physical, mental or moral.
This psychological disorder can be observed in the patient exposed in the question, who believes that undercover agents want to shut him up because he has discovered something about them.
It depends on what causing it. the only thing I can say is to drink plenty of fluids but I would recommend to go see a doctor, if you are unsure or worried.
