It's essential to remember that making a specific diagnosis without a proper evaluation by a qualified mental health professional is not appropriate. If you are concerned about your mother's mental health, I strongly encourage you to encourage her to seek professional help from a mental health provider.
That said, there are several mental health conditions that could potentially be associated with the symptoms you've described:
Paranoid Personality Disorder (PPD): People with PPD tend to have long-term, pervasive feelings of distrust and suspicion of others. They often believe that others are trying to harm, exploit, or deceive them, even without sufficient evidence to support these beliefs.
Borderline Personality Disorder (BPD): BPD is characterized by intense and unstable emotions, including extreme anger, and difficulties in interpersonal relationships. People with BPD may struggle with fears of abandonment and may perceive others as being against them.
Generalized Anxiety Disorder (GAD): GAD is characterized by excessive and uncontrollable worry and anxiety about various life situations. This constant state of anxiety may lead to a belief that others are plotting against or targeting them.
Paranoid Schizophrenia: This is a subtype of schizophrenia where individuals experience delusions of persecution and conspiracy. They may have hallucinations, disorganized thinking, and severe emotional disturbances.
Major Depressive Disorder (MDD): While depression is often associated with sadness, it can also manifest as anger and irritability. In some cases, individuals may have feelings of persecution or believe others are against them.
Delusional Disorder: This condition involves persistent, false beliefs (delusions) that are not in line with the individual's cultural or social norms. These delusions can lead to significant distress and difficulty functioning in daily life.
It is important to remember that diagnosing mental health conditions requires a comprehensive assessment by a qualified mental health professional, considering the individual's medical history, symptoms, and behavior. Furthermore, it is essential to approach the topic with empathy and support, as discussing mental health concerns can be sensitive and challenging. Encouraging your mother to seek professional help is the best course of action to get a proper evaluation and appropriate treatment if necessary.
