As soon as I could understand the rapture, I was terrified of it. I was probably only 9 or 10 years old when I understood what it meant and the Left Behind (for kids) series really did not help. I already struggled with (what I would retrospectively call) separation anxiety and claustrophobia and knowing that everyone that I cared for in my life might just suddenly disappear was a horrifying revelation. This tied in strongly with the fear of sinning and not being forgiven and the fear that I may not have been saved completely, or, more likely in my mind, have lost my salvation due to some hidden sin.
