Your lack of self-love is only a relative truth. It is true because you say it is true, and believe it. You don't need to find love, or make it, or change anything at all, because your lack is not a real truth. You only need to disbelieve that you don't love yourself, and it will cease to be true.
Either you love yourself or you don't; there's no way to change from one to the other. Whichever one you find to be true will have always been true.
