No, Pisces are not inherently narcissistic. Astrology can't diagnose narcissism, a clinical pattern of behavior that shows across contexts. While Pisces are stereotyped as empathic and dreamy, anyone of any sign can show narcissistic traits. If you're feeling drained or dismissed by a Pisces, that's valid to question; focus on behaviors, not birthdays.
Look for patterns: consistent lack of empathy, entitlement, blame-shifting, and punishment when you hold limits. If that resonates, respond, not rationalize: set clear boundaries, use short I-statements, and track incidents rather than vibes. When things de-escalate, invite repair; if they escalate, protect your distance and support network. Whether the person is Pisces or not, your safety and dignity come first.
