I hope you do too. Good for you on trying; call out your fears and try to find the root of what you fear and the why?
People will always fails us.
Try to define trust in a humanly way—and start small and with one person. Let their be room for growth and error. The process of trusting will have its cracks.
The idea is: do you trust them as a human to communicate why they can or not be there for you when things go wrong—and can they trust you to understand?
Peace! Keep well!!
