I struggle with this question quite often. I'd say I'm an agnostic due to my analytical nature. If my case, which may or may not be the majority, meditation is my best medicine. I enjoy community and fellowship at a spiritual level. It fills a void caused by the loneliness generated by BP and PTSD. I struggle more than enough with day to day challenges. The age old question of whether there is a God or higher power, only adds another layer of questioning of "who am I and why am I here". To quote Woody Allen; "You are no more of a car standing in the garage than a Christian standing in a church".
