I had this feeling last year when i had to go through a small surgery and i was really afraid of it.My surgery was after Jumma prayer and when i started my prayer and came to this ayah,"Master of the day of judgement" and something clicked in my head.I thought i was never afraid of judgement day as i'm afraid of this small surgery and that made me cry so much.I promised my self that time i'll focus on my deeyn and try to make my aakhirah better.I'm still struggling to be a better Muslim but that feeling is rare imsad I wish i pray to Allah SWT and remember Him SWT in my healthy happy days like i did in the time when i was in pain
