I just want to know if there's any way to get ready or learn to accept death and die. Something like meditation or something, IDK.

I'm not planning to go nuclear, just take myself out. I know you just can shoot yourself or drink poison but I just want to know if there's a way to acknowledge that this and do it peacefully without drawbacks.

I started to settle everything (not owning anyone nothing; gifting everything and so) slowly as I don't want to give alerts to anyone. Is just the "being ready for it" part that I need.

Any suggestions?
