How often do you think what it means to love someone else? I'm not talking about romantic love, but brotherly and Godly love you have for another person. Have you ever wondered how your own feelings toward yourself might affect you loving other people? I have.
And I have come to a conclusion: it is hard to love other people, as you should, if you don't love yourself. If one has come to dislike or even hate oneself, it is going to affect his/her relationships with other people. I base this idea on my own experience and on scripture.
