The fear of showing your true Scorpio self comes hand in hand because when you truly surrender, you get to love with a passion, sweetness, and fieriness that hook Scorpio, but receiving a stab of disappointment and disloyalty from that type when you had already been removed all the armor, it is the worst thing they can do to you because there you implant them bigger, stronger and more impenetrable and you know it Scorpio, you know it because deep down you are a very passionate person with a huge heart, with a lot of desire to love and with many internal fears that you do not want to be the scoop of the week.
