Your insecurity comes from the disappointments that other Taurus cause you. You put much faith that everyone will act like you, and when they don't, you fall apart. Also, in love, you think that when you start with someone, you may have found your soulmate, and when you lose it, you think that you have missed a vast Taurus opportunity. And unfortunately, thoughts of the type come to your mind: "I will never be able to love so intensely, or I will never find someone like that." And deep down, that's why a large part of your Taurus insecurity comes, for making your mental problems think about things that are not and will never be like that.
Please, Taurus, first you go, then you and later you. And then love will come when you love yourself first. And the loves of the past, those that in the end did not end well, are not the honest Taurus; the loves of the past are past. The best is yet to come.
Insecurity comes to you because you overanalyze your Virgo past. Very, very much. You try to understand why things have gone wrong for you, what the hell you have failed at, why others are so ungrateful, and even how you can help them. Fuck Virgo, that each one heals himself, that each one takes care of his back, ok? You are not anyone's mom or dad, and you have to move on.
Virgo is there from now on. That's where all the anxiety comes from, when you stay anchored / or where you shouldn't know when you stay anchored / or in the Virgo past. And furthermore, you know that you will never be able to look ahead like that; you know that you can even spoil your entire future by not staying in your present. Do not try to think about it and identify everything that went wrong when you only need to accept that it is over and that now a new stage begins.
You get too attached to Capri people, even though you can be ice cold and seem super distant. Well, no, to the surprise of many, when you end a relationship, you have a terrible time. It is challenging for you to overcome, forget and understand that there may be a better life after that. When he embarks on something, you are a person whom Capri gives absolutely everything. When he suddenly ends, he is left with absolutely nothing. But hey, only at the beginning. And that's where all your Capricorn insecurity comes from.
Look that you are a super independent person, but you are not so much Capri in love. You hoped that when you started with someone, that person would stay in your life much longer. But sometimes, things go wrong. You give too much almost without thinking about the consequences. Stop having such high expectations all the time. And even more so without Capricorn displays.
