Sometimes, when people are sad, nothing can really bring them back up right away. Simple words, good advice, or even the people around them trying to make them happy can't make them happy just like that. We should never tell someone to just be happy and forget about what's holding them down, because we're not dealing with the pain in their heart. It takes time and patience for someone to get back up. It's not that easy.
Oh Allah, please forgive me for all of the bad that I've done. You are so Merciful and kind, please forgive me, and help me stay away from all that's wrong. It's so hard for me, and I'm so weak but You are the Strong. Please increase me in sincerity.
