Don't be Sad
A religion that is full of benefits
Islam offers the believer a broad range of benefits and rewards, benefits that encourage him to continue upon the true path and rewards that boost his hopes for the Hereafter. Deeds that wipe out sins --- such as prayer--- are many in Islam. For example, a good deed is multiplied ten times in reward, or seven hundred, or even much, much more. Another example is hardship, because any time a believer is afflicted with hardship, some of his sins are atoned for.
(Also, during times of affliction one benefits from the supplications of other believers.)
(And if you would count the graces of Allah, never could you he able to count them.) (Qur'an 16: 18)
(And He has completed and perfected His Graces upon you, [both] apparent [i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.] and hidden [i.e. One's faith in Allah (of Islamic Monotheism), knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise,
etc ].) (Qur'an 31: 20)
