The constellation says that my personality is different from mine. Why?

Constellations are divided into three categories. The first category is the Sun Constellation, which focuses on your birthday. The second category is the moon constellation, which is your emotional magnetic field constellation. The third sign is the rising sign, which is your hidden sign and your unknown side. Maybe your birthday is close to Gemini, and your rising sign is Gemini, so it doesn't match your original Taurus.
