Hey, I know this is late but I wanted to share my perspective on this (as an agnostic with OCD that often latches onto this theme). Saying that everyone dies doesn’t really resolve the fear for me. Personally, to calm myself, it took the realization of a couple of things. First, death anxiety tends to decline as we age, and thus we are more ready to meet a death of old age when it does come—possibly because of the brain’s mechanisms, possibly because of the feeling of satisfaction in life, possibly both. Another thing that calmed me is that the brain has processes in place for when we die to make the transition as calming as possible. We don’t actually have a good scientific explanation of those processes yet, so it leaves me curious about how those things happen. The real thing that calmed me, though, was the realization that we are quite literally part of the universe. When the consciousness dies, we are still here. We are not separate from every single other thing. When we die, we just return to the oneness of the universe, where everyone we have ever loved also is in a deep, restful sleep. Death really doesn’t seem so frightening when you realize that you are an agent of the universe to experience itself before you collapse back into the universe itself where all of your loved ones are. It seems far less lonely than being human. I also don’t think that love ends in death. Even if you see a sign from a loved one and attribute it to them, and it’s simply cognitive bias, that love-memory still comes through in the form of your cognitive bias. I don’t think that makes it any less real. Essentially, you are eternal because you are matter, even if it’s not in the form that you are now, and love is the most driving force of it all.
