For what it’s worth, I had a very similar thing happen to me. I guess I never made the connection until now. After a year, my intellectual curiosity is just starting to return. That you feel repaired gives me hope.
For the first 3 years of doing almost nothing productive the progress was quite slow.
In retrospect, a couple of high dose psilocybin sessions may have sped up recovery by reprogramming some of my identity that was at the core of the stress.
