It's important to recognize that I cannot provide a diagnosis, and these symptoms can be associated with various mental health conditions. It would be best to consult a qualified mental health professional to discuss your experiences and receive an accurate assessment.
However, I can provide some general information about the terms you mentioned:
Bipolar Disorder: Bipolar disorder is a mood disorder characterized by episodes of depression and mania (or hypomania). These mood swings can be severe and can impact daily functioning and relationships. Bipolar disorder typically involves periods of elevated mood (mania or hypomania) and periods of low mood (depression). Violent fantasies towards oneself or others are not typical symptoms of bipolar disorder but could be related to other conditions.
Splitting: Splitting is a term used in psychology to describe a defense mechanism where a person sees things as all good or all bad, without acknowledging any gray areas. It is commonly associated with borderline personality disorder (BPD) and can affect relationships and self-perception. Splitting can lead to rapidly shifting emotions and perceptions about oneself and others.
Experiencing fantasies that fluctuate between positive and negative extremes could potentially be related to splitting. However, it could also be associated with other conditions or factors. Aggressive and violent thoughts towards oneself or others are concerning and may indicate underlying emotional distress that should be addressed with a mental health professional.
It's important to remember that self-diagnosis can be unreliable, and only a qualified mental health professional can provide an accurate assessment and diagnosis. If you are experiencing distressing thoughts or mood swings that impact your well-being or daily life, I encourage you to reach out to a mental health professional for a comprehensive evaluation and appropriate support. They can help identify any underlying issues and create a suitable treatment plan to address your concerns effectively.
