If you're concerned about your behavior and its impact on others, I strongly encourage you to seek help from a qualified mental health professional.
That being said, difficulty in empathizing with others, saying harsh and arrogant words, and a lack of concern for others' feelings could be indicative of various conditions or personality traits. One potential consideration is antisocial personality disorder (ASPD), which is sometimes associated with traits commonly associated with sociopathy.
However, it's crucial to recognize that diagnosing any mental health condition requires a comprehensive evaluation by a licensed professional who can assess your thoughts, feelings, behaviors, and other factors in your life.
Regardless of the specific diagnosis, if you feel your behavior is causing distress or negatively affecting your relationships, seeking professional help can be beneficial. A mental health professional can help you gain insights into your feelings and actions, develop coping strategies, and guide you toward positive changes.
Remember, reaching out for support is a sign of strength, and it can lead to personal growth and a more fulfilling life. If you're unsure where to start, consider speaking with a therapist or counselor who can guide you in the right direction.
