Forgive yourself for any sins you may have committed. You need to let go of past mistakes and work on improving the future. Whatever has happened is done. It is in the past and there is nothing you can do to change it or better it. The only thing you can do is forgive yourself or use those negative experiences as motivation to get better and do good.

Understand that all shall be well. Allah forgives minor sins for He is All-Understanding and All-Forgiving. Even if you feel that you are already too deep in sin to turn around and become the good Muslim that you truly are.

The Prophet (sall-Allahu `alayhi wa sallam) said, "There is a pillar of 'Nur' (Divine Light) in front of a `Arshi Ilahi (The throne of Allah) when somebody recite 'la ilaha illa-Allah', this pillar start shaking .when Allah asks it to stop shaking it says "how can I stop when the reciter of the kalimah has not yet been granted forgiveness" Thereupon Allah says, 'Well I have forgive him,' and then that pillar stops shaking.”

The only lasting beauty is the beauty of the heart.
