who am i?

I have been asking this question from myself from quite some time now. who am i? what am i doing here? wats the purpose of my life? isnt this world only a temporary place? so why do i even care for the things going in my life? i shouldnt care even if i think that im being treated unjustly. even if my dreams are shattered. even if i know that nobody loves me. why do i care? this is only a temporary place.
what am i doing for my life after death? its not going to end ever. so why dont i care about that life? why do i keep on thinking about this life so often? why am i so sensitive? why do i even care :(
i love u Allah
pls forgive me
and make things easier for me. aameen
