Well i have boarderline personality disorder and sometimes i have something similar. i reffer to how im feeling as if someone else is feeling it, "she is confused and i think its becuase.. blahblahblah" reffer to myself in third person. or depending on how extreme my mood fluctuations are (with the bipolar side of my schizoaffective) it feels like im a diff person some times from manic (a child, [extreme energy and impulsive]) to depressed (an older person [sluggish, irritable, grumpy, tired all the time and slow])

When it comes to me talking liek that, i do it becuase it gives me a bit of space from myself and the extreme emotions im going through. so with being able to distance myself im able to talk about something painful. and not just be sitting there crying without being productive.

as for the moods, i think i just see it like that. but personally, dont actually reffer to myself as anyone different, just to gauge how im feeling and realizing my mood at that time is not "normal". its how i am able to understand and tell myself that something is seriously wrong.

Hopefully this might have helped. good luck and sorry to hear your having troubles
