To be honest, I can't say I've had anything quite that bad, but I can sort of understand what you mean. I think. I think the thing with dissociating is that it feels like you are sort of leaving your body for a little while, and then when you come back everything is all wonky. That's how it is for me, anyway.
I know of another forum that's open to DID too;
Self Help Place (The creator asked me to share it with people, so I promise I won't edit the link at all this time!)
