For me:
pdoc = psychiatrist (as in medical doctor)
t = therapist
tdoc = psychologist (as in non-medical)
cycling = shifting from any mood to another (normal to manic, manic to depressed, whatever)
cycle = the phase of mood (what mood is currently.)
episode = times when a mood becomes sever enough to be disruptive, or an explosive mood happens
mixed = depressed and manic together.

Tha's all I can think of for me.

oh also there is rapid cycling and ultra rapid cycling. Rapid cycling I think is more than 4 cycles of each mania and depression in a year. Ultra rapid cycling is people who seem to be shifting a great deal of the time.
