We occasionally feel like our sins are too heavy to be lifted off our shoulders. We may feel undeserving of forgiveness, but Allah forgives. He forgives whomever He pleases. All we have to do is ask. We must take the time to sit down and genuinely repent for our sins. Allah knows what is in our hearts. He knows how guilty we feel. He also knows the sincerity of our repentance. So do not feel hopeless: pray. Ignore everything in the world and genuinely ask your Creator for forgiveness.
