@shoegal Not being able to do an online group would make it tough, because many of us with severe chronic pain don't drive or go out much except to doctor appointment--either because of the underlying condition, or mobility problems, or because meds make us too drowsy. Since you're concerned about privacy, is there any way you could use a username that doesn't reveal your identity? You can always get a second or third email address just for a group.
I'm no expert but I have the impression that there are support groups for different health conditions, both online and in-person. I found a bunch of resources including support groups for a friend with Parkinson's at one of the national Parkinson's organizations. If you've mainly looked at a support group for pain, maybe there is one for another condition you have. Good luck!
