Hmm, when I've been depressed, I can't remember ever being happy about anything and always say, "this has been going on my whole life!" It's quite ridiculous really, though some moments of clarity leak through and the whole idea becomes a joke.

Oh no, I spilled some milk....end of the world! My whole life is ruined or some such, where milk is actually acid eating away my guts and the pain!

Right, as for being "manic" I don't know, never really stop to think about it but, I haven't had to either. I remember being driven, euphoric and angry, inspired and excited and it is other people who label it.
