When we're caught in fear, sometimes "faking it until you make it" is the only way forward.
We won’t always be overflowing with feelings of radical love and unconditional self acceptance. These things do not happen overnight, much as we might want to will them into existence.
Rather than shaming ourselves for our experience and for not “being further” when we get caught up in fear and negativity, we could experiment with asking questions like
“How would someone who feels worthy talk to themselves?”
“If I really loved my body, what would I eat? How would I move through space?”
We cannot force ourselves to feel something that we don’t, but we CAN practice forming new patterns and new ways of existing in our mind and body. The more we do this, the more it will become second nature, until one day we might even find that it’s become our reality.
