welcome to HCM
Having suspiciousness, social withdrawal, magical thinking, fear, increased aggression and restlessness may be a sign of severe problem. As per my opinion it should not be overlooked because it may be a feature of Prodromal Schizophrenia. Schizophrenia is a psychotic disorder
that is characterized by various clinical symptoms like delusions of prosecutory type, hallucinations
like auditory, suspiciousness, social withdrawal, severe social and occupational dysfunction
So as you are having a lot of such clinical features please discuss with your mother regarding the problem and visit a psychiatrist
for expert opinion ASAP.
hope I cleared your doubt.
