Newly Diagnosed ADHD (and Likely Autism) – Now What?

Hey everyone, I could really use some advice from fellow late-diagnosed AUDHD folks.

So, a bit about me: I’m a 27M who spent the last 8-9 years being misdiagnosed with depression, anxiety, and a long list of other things by multiple psychiatrists. Turns out, the real culprit was inattentive ADHD (that life-sucking executive dysfunction).
Just last week, I finally got an official diagnosis from the government—which means I now have access to stimulant meds. Finally! (They’re ridiculously restricted here, like having-a-nuclear-bomb-in-your-basement levels of restricted.) On top of that, I’ve recently realized that I’m most likely high-functioning autistic (aka Asperger's), and just really good at masking.

For years, I thought I was just socially awkward, anxious, or maybe a little broken somewhere inside my brain. Turns out, I’ve been playing life on hard mode this whole time, constantly masking and camouflaging without even realizing it. And now that I have this clarity, I’m sitting here wondering… okay, so what now?
For those of you who’ve been through something similar (late diagnosed/high masking):
How did you process this whole discovery?
Did ADHD meds help? Did they actually improve executive dysfunction?
Did you try therapy? Was it useful, or just another expensive attempt at becoming "normal" (which, let’s be honest, is never happening)?
Looking back, what do you wish you had known or done differently after getting diagnosed?

Right now, I feel like I just unlocked the biggest plot twist in my life story, but I have no idea what to do with it. Any advice, experiences, or general wisdom would mean a lot!
