Have any of you wondered if maybe you've been misdiagnosed?

I was diagnosed with borderline about 3 years ago, did DBT, all of that. It took 11 people to diagnose after an OD me but I almost wonder if it was a was a 'waste bin' diagnosis. If I look at the traits:

(1) frantic efforts to avoid real or imagined abandonment. -No.

(2) a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation-Not really, no. The problem is my mother likely has borderline so my relationship with her has been pretty unstable. I don't really devalue or idealize my boyfriend, either, I'd say. This one is kind of hard because I'm a very anxious person.   

(3) identity disturbance: markedly and persistently unstable self-image or sense of self-Not really, my self-image is stable. 

(4) impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, Substance Abuse, reckless driving, binge eating). 
Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5. -I'm not impulsive at all. I'm a hugely inhibited person. 

(5) recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior. -I tend to feel suicidal under extreme stress, and I think about it a lot, but again, this doesn't seem to stick. 

(6) affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days)-my moods tend to be pretty stable when my life is stable, but very unpredictable when I'm under stress. 

(7) chronic feelings of emptiness-again, this only seems to happen under stress.  

(8) inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights)-No.  

(9) transient, stress-related paranoid ideation or severe dissociative symptoms-I dissociate a lot because of some abuse as a kid-I tend to shut things off. But I don't know if this fits, either. 


All in all...I just sort of wonder sometimes if I've been misdiagnosed. Two key traits seem to be impulsivity and extroversion, of which I have neither.

Do you guys ever wonder if you were misdiagnosed?
