You're a Jerk

Although I'm not a licensed psychologist or psychiatrist equipped to make official diagnoses or provide medical prescriptions, I am incredibly confident that you are a compulsive liar, you have an external locus of control, and you suffer from a mental disorder like APD (Antisocial Personality Disorder), BPD (Borderline Personality Disorder), or NPD (Narcissistic Personality Disorder).

Despite the apparent presence of those undesirable characteristics, I have yet to describe your worst quality, which cannot be entirely explained by mental illness. In simple terms, you're an unapologetic jerk.
