What can I do to restore my happiness and smile, after reaching a point where the only thing I enjoy is listening to the Holy Quran?

Allah's love for listening to the Quran and the heart's expansion at it is a great favor, for Allah Almighty says: "Allah has sent down the best statement, a Book consistent and oft-repeated, from which shiver the skins of those who fear their Lord; then their skins and their hearts soften to the remembrance of Allah. That is the guidance of Allah by which He guides whom He wills. And he whom Allah sends astray - there is no guide for him." One must thank Allah for His blessings and not despair, for life is full of blessings that Allah has bestowed, such as the sun, the moon, and health, and He has commanded us to be grateful for them. Supplicating for the betterment of this world and the Hereafter, and asking for an increase in every good in life, as the Prophet, peace and blessings be upon him, prayed, and that rejoicing in Allah's blessings is better than accumulating worldly possessions. Happiness and misery originate from within the soul; whoever is content will have contentment, and whoever is discontent will have discontent.
