Afraid of death

Cold Moon
So I've been having panic attacks this past month thinking about death and what comes after. Nothing is comforting me. I grew up in a semi religious family, as a christian. I don't know if I fully believe any religion, it all seems so surreal. I try to talk to people about dying but I scare them and no one wants to talk about it. Has anyone else struggled with the thought of dying? I have serious anxiety, haven't been able to sleep or eat regularly and it consumes my thoughts. Idk how to get it to stop. Idk if finding a faith would help either because I am rather skeptical. My dad and religious friends in my life are like oh don't worry everything will be okay BUT NO ONE KNOWS and that is so fucking scary. ); help
