But if it's still too hard for you to comprehend or at least accept this reality, you can hear it in a religious tone. I can't say a lot about Abrahamic religions, Indic religions don't define death as the end, Here's what krishna said:

"The Spirit is neither born nor does it die at any time. It does not come into being or cease to exist. It is unborn, eternal, permanent, and primeval. The Spirit is not destroyed when the body is destroyed."

"Weapons do not cut this Spirit, fire does not burn it, water does not make it wet, and the wind does not make it dry. The Spirit cannot be cut, burned, wet, or dried. It is eternal, all-pervading, changeless, immovable, and primeval. Atma is beyond space and time." (Both refer to the idea of being "you" not dying by the mere destruction of body)

And the most fomous one, "I am become Death, the destroyer of worlds" (death is a part of god.)

So, if it eases your mind, then you can believe that you have a soul(spirit) and that you'll be reborn or whatever. I personally don't recommend this way, but I have seen that this has helped some of my friends who were going through this existential crisis.

I would still prefer the "we are the universe arranged in a certain order, and that the change in this order means death, but either way, we are still the universe."
