CMV: Death is terrifying

I attended a funeral of someone who died very young (23). I really hate that I went to the funeral because ever since then I’ve been obsessing over death and how scary it is. Literally everything about it is scaring me. 

The main things that worry me are:

- The unknown that comes after. Is there something after or do you just fade into complete nothingness for eternity? 

- The process of dying. Does it hurt when your organs are shutting down? They say your brain still works for about 7 minutes after your heart stops. That sounds like sleep paralysis that you won’t be waking up from. 

- Decomposition. The thought of my body decomposing in some casket underground is terrifying. I hate that I have these thoughts but I can’t make it stop. 

I try talking to people about it but they just tell me how I’m only 21 and shouldn’t be worrying about it. Please help!

I don't want to scare you any more, but there is nothing that you can do to never die. It will happen to you eventually. Earth could be hit by a meteor that kills all of humanity. You could get hit by a car that swerves to avoid a collision. North Korea could nuke us.  
   
Eventually, what has happened to billions of people before you will happen to you, and you will die. But that did not stop most of those people from living their lives. Don't worry about what you can control, and just focus on what you can.  
  
In regards to the process of death, and what it is like afterwards - just think about it the same way as before you were born. Nothing.
