Be better and trust Allah! You will die without any doubt! Thinking about it in this negative way is a trick from Satan trying to depress you and maybe make you exit islam.

Im terrified of dying as I heard it’s painful, will it be painful? I’mscared that after so many good deeds at time of death I do something that makes me end up in hell as the devil tries to get you leave religion?I’m not 100% bad nor 100% good but it’s hard to have hope when all of it is scary. From the description of munkar nakir to day of judgement it’s hard to imagine believe. Please advice?
