Autism is that taken to its logical extreme, but I'm not aiming for that.
And there is no feeling of adrenaline! It's just excitement or anticipation! XD[/QUOTE]
Maybe only the most severe cases of Autism, otherwise not.

It's called adrealine rush, because your body is pumping in adrenaline(not be obvious, but that's why it is called so).
But those aren't emotions, those are moods(or, are they same(?))![/QUOTE]
Moods and emotions are pretty much the same thing although moods are generally a bit broader I suppose, but they are completely dependent on the emotions youre feeling at a certain moment.
But being hyper active due to having adrenaline pumping through your veins is not an emotion or a mood, but a state of being I suppose. Adrenaline isnt related to emotions, its just a way to give your body extra energy so you can run in a case of danger. Though of course this has emotions associated with it such as fright, tension, anticipation etc, depending on the context. But being hyper active itself, is not an emotion.
And the Solitude that you described comes closer to being in a catatonic state rather then it being some sort of emotion.
