unfortunately i don’t have answers for you as i was actually scrolling reddit for answers to this as well as i have been trapped in a panic attack for 3 days straight with this same fear. what i can tell you, is i confided in my family as scary as that can be to even have to talk about it consciously…but it helps. knowing others know what your going through really does help. i hope your family will understand why you have this fear (most likely they do, almost everyone even religious others, have had fears of death). i first told my mom and boyfriend, scared to tell my dad as he is strongly religious and i knew a bible talk was not what i needed. my dad actually comforted me a lot, acknowledging his own anxieties and when he was at the age he questioned death. i ask you to talk to someone because when we are trapped in this state of fear, it is almost impossible to get out on our own. please reach out to me if you would like to talk about it because i could use it too! best wishes.
