Just out of curiosity, do you also have social anxiety? I was raised christian as well, and I had a lot of trouble sitting through sermons and things like that (especially as I got older) due to it. I didn't know I had ASD at the time, but I feel like both together can make this rather difficult.
Being somewhat a believer in a higher power now (after a very long period of atheism), every time I even vaguely think about the idea of going to church, I remind myself about how hard breaking through that barrier would be. Although, I do think it's possible to get desensitized over time if someone is committed to it anyway.
If I had the means to do it, I'd absolutely use that as a means of reconnecting with people in a somewhat-intimate setting. Sometimes I think problems like SAD stem from a lack of that 'fellowship', or at least that's what I see in myself quite a lot these days. I think this is just an overly-complicated way of saying that I need the holy spirit to enter my life, but I guess it depends on how you look at it!
