Please read Surah Taha if you feel down. Read with its translation word to word and reflect on its meaning. You will find so much comfort in the Quran, your heart will soften with His beautiful words. Your heart will find ease only if you let it.
“No person who is afflicted with sadness, hears (listens to) Sūrah Yūsuf, except that he is comforted by it.”
— Ibn Atā رحمه الله, Tafsīr al-Baghawi رحمه الله of Surah Yusuf
