I too have a bit of disbelief. There aren't any markedly no sleeping for days that I've experienced. I do know that no one is the same and you don't fit into some cookie cutter box of symptoms but isn't the no sleeping kind of a trademark?
For me focusing on the high functioning part would be my focus. Forget the labels and just work on what symptoms you have. If you can do that then you will be fine. Just be honest with your support group about your symptoms and proactive in your own balance.
