Im trying hard to change

Today, service was great but when i enter into Church today, i felt the sense of regret and unforgiven and the only part that i struggle with was when Wei Chen asked me whether my sins were forgiven and i couldnt give him an answer coz there were sins that i cant forgive myself and i dont think that HE will forgive me. Even, if HE forgive me, i feel that i dont deserve.

God presence was there but i couldnt feel him and im drying to feel his presence again. I really want to feel his presence coz i haven been feeling his presence for quite long already.
