The book Hiroshima by John Hersey has many accounts like this. It’s a short read and follows six people and covers the first year after the bombing. I’d highly recommend reading it if such accounts are interesting to you.
Fun fact the cover image if this edition was kind of a decoy (perhaps to accentuate the shock): https://www.newyorker.com/magazine/1946/08/31
As an aside I would never had guessed this artstyle was a 40s cover.
