Could really use your advice / encouragement.

After 36 years of spinning my wheels unfocused, scatterbrained, and anxious, I was finally and recently diagnosed with ADHD. Medication has begun and I've noticed some improvements, but there's still a long way to go.

My struggle with ADHD and its severe deficiencies in executive function and memory have made it near impossible to: 1) accrue knowledge & experience in real-time across my career, 2) recollect the information that may have actually made it through to my brain, 3) play long-term strategic games, resulting in a lot of burned bridges and unfinished projects.

In an effort to jumpstart my career, I've spent the past year applying to jobs in my field and while there's been a good bit of traction as far as being invited to interview, my interview performance is so laughably abysmal. I cannot access any information when needed. The information I do have access to is fragmented and scattered. Rejection sensitivity creates a suffocating urgency to impress and be perfect. I can't be "myself."

The sum total of these challenges is that I am in no way capable of inspiring even an ounce of confidence. I look good on paper and crumple in person. I know I have potential, but I need more time than a 30-minute call allots to show it. At this age, no one is hiring for potential and no one is willing to give me a chance. I don't blame them.

I feel like I'm operating with half a brain, and that half is atrophied over the years of blank-mindedness. I struggle to think in detail. I struggle to think in a clear and structured way. I just struggle to think. I feel cognitively impaired.

How do I even begin rebuilding at this age? I want to be skillful. I want to be a leader. I want to contribute meaningfully.
