An Advise..

[Abu Hafsat]

As-Salaam alaikum, 

Says the Noble Messenger of Allah, Sallallahu alaihi Wasallam, "ITBA-S-SAYIAAT AL-HASANAH TAMHOOHA.. Follow bad deed (you may have done) with a good deed, as it (will) erase it". (Tirmidhi) 

When you commit a sin, immediately follow it with 'astaghfirullah' : that will erase the sin. Don't say, 'I have too many sins'. No, do not complain or it will be as if you are contradicting the verse of the Holy Qur'an :

"Remember your Lord (Allah) when you forge" (18:24)

So, whenever you commit a sin, something bad, follow it with goodness and it will erase it. 

Many Regards.
