You're scared of being vulnerable but here's the truth:

it's the only way to find happiness.

Your heart is too genuine and kind, too sweet and authentic, to keep it hidden away. I promise you that opening up to someone will only let a river of love and acceptance come your way. Not everyone is going to hurt you or betray you or make you feel like less than you are. You will learn to spot those people, you will kick them out, and you will eventually find out how much you really are worth.
