when you felt so ashamed with what you did that you don't even want to face people, ask him for courage because it is always easy for ALLAH because He always has the power to do that. Sometimes we don't even realise that we just did it...bravely go on with life even tomorrow seems so scary and hard to endure. it was Him who give us the courage to move on and to be able to forgive ourselves...
when we are happy...thanks to Allah for the happiness He bestows on us..savor the happiness and always be grateful..be happy and grateful for what He gives to us and be happy for what He did not give to us because sometimes, we want something so badly but we did not get it because He knows best what is best for us. what we love@like might not be the best for us, so, always have faith in Allah.
