Has anyone been to a "Blue Christmas" service? [View all]

Sometimes called a Longest Night service?

I first heard about this a few years ago. Kudos to the Christians who are doing this - I think.
I have left the faith of my fundie parents behind me, but I still am sympathetic toward what I feel Christianity is SUPPOSED to be.
And, I happen to think, this is a good example.

I'm thinking of attending one, because I am in a LOT of spiritual, emotional, intellectual pain.

However, I am terrified of American Christianity right now. Not sure any of them are to be trusted.
Don't want to walk into what is supposed to be welcoming and loving and find out it's not.

Wondering if any of y'all have attended one and can recommend or not.

Thanks!
