Well, it's good to hear you're off the drugs & alcohol! Those kind of exacerbate the initial problem.

And it's also good that she's still planning on keeping therapy with you after the dx. Most people won't bother or they'll act all ****ing victimised for no reason! So... I'd definitely stick with her. She sounds decent.
As for getting a dx? Hasn't been formally recorded, thankfully. But it was strange vs. surprising to be even informally categorized as such. Made sense the more I analysed it though. I've been dx'd as conduct disorder when I was a child & had some disconcerting behaviour but it never really occured to me that it was an issue. Everyone just finds me "quirky" & pragmatic/blunt/abrasive, so no one's ever brought anything to my attention.
It has not a great deal of impact on my existence unless I'm in a manic spell, where it goes haywire & starts to cause significant difficulties/impairment. Usually I am able to run on an autopilot-like setting where I am able to keep myself pacified & out of trouble. So it wasn't really until my Bipolar surfaced that it made any difference in my life whatsoever... Never really considered it beforehand. I was just operating under the impression that I was a very reasonable individual. It's still silly to me that not acting like everyone else is means for a diagnosis, but whatever. Hahah!
