Adult adhd problem. Under high pressure.

I am a 24-year-old male seeking an evaluation for Adult ADHD. Looking back at my life patterns, I strongly suspect my brain operates on an executive dysfunction and dopamine-deficit model. My core symptoms are: All-or-Nothing Focus: I struggle heavily to focus on routine or uninteresting tasks. Even if a study topic interests me initially, I abandon it the moment the novelty fades. Hyperfocus & 0-or-100 Mindset: When a task excites me, I get intensely locked in, forgetting food and sleep. My lifestyle has no middle ground—either I give 0% effort or 100% flawless perfection (e.g., in dressing or projects). Thriving in Crisis: I am entirely fearless and highly functional in chaotic, high-risk, or fast-paced situations (like high-speed driving or hard physical challenges) where others panic. I feel naturally alert only under high pressure.
