You have such an interesting case. Defining weird is always a weird process. You know what, though, I've got a, not a theory but, a potential tree to bark up upon. I saw this TED talk (linked below if you're interested) talking about the two leading theories of emotion.
One is cognitive expectation stuff. The mind constantly setting up for appointment/disappointment as part of it's day to day function. (And then rewarding/punishing itself for the results.)
The other is bio-emotional feedback stuff. Like what you're describing. The shakies and the butterflies. The body neurology trying to be recognized.
I think both theories are connected. I also think you could bring this to your psychologist and get some old-school analysis accomplished out of exploring these sensations.
