Oh, I know the fear you feel very well. You are the center of your own world. Everything you've ever known has been from your P.O.V. So it's only natural for the idea of you suddenly not existing to scare the shit out of you, even if you know you won't even know about it.
1850 and 2150 are totally different. I can easily find out what happened in 1850 because of history. None of us here will ever know what happens in 2150. We'll be gone and the world will carry on without us and forget we ever even existed. Photos of you will be discarded because nobody will know who they are even of anymore. Everyone you care about will die, too, and all the things that hold sentimental value to you will be thrown away or sold to strangers.
That's terrifying, but forcing yourself to believe there is an Eternal afterlife just to diminish that sense of terror sadly won't change reality, no matter how desperately you want it to.
