Is it normal to hurt over the thought of death and the devil ?

thank you so much and I know it sounds silly but it's a seriouse problem...i felt alot better posting somewhere other than making someone else I personally know hear it :/ i always tell god i know you let me suffer because i love you and people with really pure hearts suffer the most because they see all the beautiful things in this life that noone else can even notice when it's right there in there face...and people like us see it still..far away
