Epicuran here.

I recently had a brain infection (from a dental cleaning — but it’s very rare, so don’t let this keep you away from the hygienist) and was close enough to not making it that my brain surgeon said multiple times “I am very worried about you.” No time to go through the Kubler-Ross ‘stages’, just went straight to acceptance. I was expecting nothing at all after I passed — and was OK with it. I was trying to follow Epicurus’ example, remembering all the good bits to make the pain less important, less ‘real’ — when I could manage to stay awake.

That said, I don’t think Socrates (as written by Plato) and Epicurus (what little there now exists due to the early Church trying to expunge his writings — notably Lucretius) were not that very different. For Socrates, non-existence was one of two possibilities. For Epicurus, it was just non-existence.
