Someone who is so closely involved with certain fandoms (whether it be a book series, a tv show, a celebrity, etc etc) that it completely destroys their mental health and social life. Someone who can't go 10 minutes without thinking about their obsession and crying silently to themselves. These types of people have had their lives taken over, so don't act surprised when you find their secret shrine at the back of their closet.
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.
