I feel almost 90% aligned to your story…
Was diagnosed formally in my 40s… Described as “super high functioning” by my psychiatrist, but really just felt like I’ve white knuckled the years from age 8…
DM me if you want to chat…
[Edited to add]: 90% of my coping mechanism were self taught and had large similarities to what you describe.
I have burnt out completely twice and the recovery taught me to develop better coping methods.
My recent diagnosis has given me the final piece to better understand (retrospectively) how and why I’ve operated and grown the way I did.
Medication is actively helping me overcome the largest remaining parts as my career has become more senior and exec function failings became more pronounced.
Unsure if that is helpful to you, but I’m also happy to chat more thoroughly in a less open forum if you’re interested or think it might be helpful.
It’s also OK if just knowing you’re not alone was what you were looking for…
