Sounds like the Wellbutrin has kicked you into high gear.

I'd consult the doc and get off that before you start drag racing to work anymore. Every AD I've ever tried has made me manic. Gotta love that feeling though. It's addictive, I think - for me anyway. For everyone else it's feeling great...too bad for us bipolar's it's a pathology.
I'd shift things down a notch if I were you. Stay away from everything that fuels the fire and keep telling yourself everything is calm and serene. And if that works, then great cause it's never worked for me. Nothing like riding a metaphor to pick you up in the afternoon
Good luck.
