I am currently reading your 'Letters to God' book, and I have to say, we may be kindred spirits. When you described your struggle with fanfiction... You described almost to a T, what I was, and still am going through.
I had an addiction with Dramione fanfiction. I read it all day, every day if I could get away with it.
I asked God to help me and save my soul, because I knew what I was doing was wrong, and yet, I couldn't bring myself to stop.
Then one day, I just didn't feel the need to read it anymore, that urge to to hide myself away in my mind, to lose myself in that fantasy world... It just went away.
I am now still struggling, I struggle to read my Bible, I struggle to pray, I am feeling doubtful about God.
I feel these thought creep into my mind, "is God even real?" Even though I know God is real, even though I have received numerous signs, dreams, and vision from God I still find myself doubting.
I feel like I'm being pressured to pray, pressured to read my Bible, everyday I feel like I'm doing something wrong, I have all this worry and fear that if I don't read my Bible read a certain amount of times a day, or if I don't do something as simple as wipeing up the water around my sink after I wash my hands that I'm going to Hell, that when the end comes, I going to get left behind.
It sounds silly, doesn't it?
