The most important thing: come to Ritual. Half dressed, half asleep, hot mess ugly crying, it's all welcome here!
Other suggestions:
Set up your camera so you can stand up when you speak.
You may want to cuss and yell. We'll cheer you on! Being in a private space where you feel free to say the thing is nice.
I light a candle at the beginning of ritual. You might want to have a candle to light, too.
Plan for 90 min. Leaving early may leave you feeling more teased than satisfied.
