tess - I researched and walked away too. Sometimes our circumstances and whatnot cause us to need more time. ((hugs)) I walked away in 2001 and started going back in 2005. When I first started my tenative steps back I also tried to live the Orthodox way without going to services. Honestly, it was kind of hard. Like you, I didn't know what I was doing....plus I was disconnected from the Orthodox community. I wouldn't worry about fasting. If I were to do it again I'd concentrate on prayers and reading one of The Lives of the Saints each day. I recieved a lot of encouragement by reading them back when I was first entering the church.
that said I wouldn't let the almost 2hr service hold you back. Maybe because I had a long experience with the Charismatic movement, which easily have 1.5-2hr services, it didn't bother me. I would gently encourage you to give it a try - at least a few times. The long distance, I know, can be daunting... especially if you have small kids.
PM me and let me know where in VA you are - if you don't mind. Maybe there's something you didn't find the first time.
