Question:
Is there a reason why my whole life is chaotic and emotional?
Astrological perspective.

Lot’s of Pisces (Moon in Pisces, Sun-Neptune conjunction), Aquarius (Moon-Uranus conjunction, Sun in Aquarius) and Scorpio (Moon and Venus in the 8th House, South Node is in Scorpio) energies.
Basically it’s a lot of chaotic (Aquarius) dramatical (Scorpio) emotions (Pisces). Note that the author of the question is 18 years old.
