When someone says "all swans are white" someone saying "my swan was black" is useful because it makes you realise that maybe you're wrong and need to rethink. someone saying "my swan is white and I've seen some swans my friends own that are white" is less useful because it doesn't provide much on top of what you've already said.
The point I was making was to contradict the idea that it can _only_ be described as extreme sadness, but in no way discounts that as an experience.
Sorry you got downvoted for that, I for one found our different experiences of this disease quite interesting! Though I'd much rather nobody experienced it...
I realise that my post does sound critical. Sorry for that -- I didn't intend that harshness.
