Hey, lady friend.
It sounds like it might've been some severe dissociation. Sounds like you just "went away" and no one stepped in from what your friends say. I do that lots in a planned way now...a long tub, etc.
When I didn't schedule it, it would happen unexpectedly. Have you been really tired, nervous, etc? I used to do it more when tired, nervous, etc.
Try to get really good rest and make sure to schedule some "zone time" for the next week or so, so it doesn't come when it's unwanted, ok?
We're here and listening.
