Allāh ﷻ sent us to this life, to this world. Don't question your existence in dunyā. Instead make shukr to Him ﷻ, be patient in dunyā and earn for the Ākhirah as Allāh ﷻ gave you this chance. This world is a place of tests. First you must accept your Creator ﷻ, then His ﷻ favour, and then accept your condition. If you accept, and are patient, then you may be in comfort, in shā’a Llāh.
