I need help from Atheists...please?

Um, I don't know how to put this, but here it goes. I'm 18 at the moment, at around the age of 14 I went through a stage in which I was cast under a religious spell of some sort. At the time I was experiencing some very difficult issues in my life. My parents were had just divorced and were constantly fighting with one another, I was stuck in the middle and didn't know where to run. I was living with my grandparents who were very much a pain as much as I love them, and I became VERY spiritual. I believed that God spoke to me, I humbled myself to God and detested all people who doubted His existence. Some of the things I said, now, in retrospect, look peculiarly like the things many of the fundamentalist Christians are saying on Yahoo! Answers. I was convinced God was there, but I am now ashamed of myself for having such a misguided past. Have any atheists on here once been believing Christians who looked scornfully upon atheists?
