Flying away is when you leave the place you grew up, by yourself, and you also leave your family (but not forever), usually to somewhere that is different than where you grew up. You don't have any intentions of returning, and you are leaving behind everyone for a better life.
an example of flying away is when you grow up in the midwest and move to the southwest coast in California because you hated cold weather, you are only coming back to see your family.
church hurt is where you experience a degree of distance, pain, or judgement from your church community. Essentially, you are just unable to “find your place”. This is prevalent in the Christian community, but can be extended to other religions.
Now that I am an adult I am beginning to heal from the church hurt that was inflicted on me as a child.
