The person you decide to love unconditionally is a HUGE investment! Make sure you look yourself in the mirror and ask yourself what you're about. Love yourself before even attempting to love someone else. Also, know your self-worth. If your voice in your head is mean to you, please understand that it’s not actually your voice. Someone else put that voice there. Someone else planted their insecurities on you because they weren’t happy on the inside. It’s on you to be aware of that and gradually start pushing that voice out.
