It is not: “how can someone love you if you don’t love yourself” but rather “how available are you to receive the love that is being offered to you”?
Of course you are lovable and loved and worthy of love in every single moment of your life. How you feel about yourself has nothing to do with being loved by others. It never has and it never will.
The work is not in learning to love yourself, or in creating the perfect conditions for you to be loved in (that doesn’t actually exist). The work is learning to slow down, soften and open yourself to love so that you can actually receive it.
Love is always there, and it’s always available to you. You don’t have to work or hustle for it. But you do have to see it and let it in.
