See through the fear
Ask yourself what you sense when you hear the word, 'safe.' What does it entail? Perhaps you imagine the feeling that the heart is totally fulfilled and all is well. Perhaps the mind suggests this is a mental understanding that you are free from danger or threat. Somewhere, in the deepest part of oneself, unwavering security is.
Consider what enables you to feel free from worry and what forces or situations trigger it. Notice common threads or patterns. What prevents you from experiencing an unwavering sense of security? What if mind is the start and end of fear? How does it resonate to begin to see though your own self-constructed illusions?
"Whomever can see through all fear will always be safe." -Tao Te Ching
