Which are the most fearful and reflective Surahs in the Quran?i

[majormuss]

I desperately want to turn my life around from a particular sin. What surah's and ayaats from the Quran would recommend for me to read and think about? Jazakhallahu Khaira

Al-Mulk always leaves me speechless, this surah is a definite.
Al-Qiyamah is one that would keep you fearful

SubhanAllah these work for me, take a look into it InshaAllah
