I'm still not sure how I feel about it. Over the years I've developed a narrative that explains away my utter failure as a student, the huge highs and lows of my professional career, my distrust and lack of respect for authority of any kind, and my pride in my achievements as an autodidact. I am a non-conformist I'd tell myself, a rebel, an independent thinker, yes a frequent fuck-up, but also a drug user, a risk taker, and someone who sees the "small stuff" as beneath them.
Now the narrative is becoming: "I have a neurochemical condition that affects attention, impulse control, and executive function which causes me to seek novelty, and drives a need for stimulation and engagement." Honestly, I like that narrative a lot less.
I suppose it's somewhat of a comfort knowing that there is a fairly common condition that goes a long way towards explaining my life, but it does seem to take the personal choice out of it.
