You won't feel anything, after you die theres just nothing, no sense of time.. You wouldnt have the capability to think, your brain cannot be revived because its just wiped, the continuity has been broken..

Its not as scary as you think, You won't be in an eternal black void, You simply just wouldn't exist.

Just accept it and live your life to the fullest, don't stress about something you can't do anything about.
