Pay no attention to Defd...he just hasn't been able to figure out what to do with his Saturday and Sunday mornings yet that doesn't involve and suit and coffee break. Makes him a little bitter.
What to do? Well...I tell you, I felt very odd and lost when I left. I had already rejected a lot of other religions based on what I believed as a witness, so I thought about those some more, and read. I personally came to reject the bible as some sort of God written rule book. Don't get me wrong, I am not trying to offend anyone, just relating my experience.
If you are up to it, start your search, but my advice would be to don't rely soley on the bible to base belief systems. Use rational thinking as well. I don't know where you will end up, but I think you may be able to avoid many mistakes if you try to be rational. Reason is very important, I think.
By the way, you don't necessarily need a religion for a belief system or philosophy.
Good luck...you will find your way.
