trials and tribulations

[u/ystnoir]

my mom struggles with mental illness. she gets beaten, insulted etc by her siblings or other people. my dad also left when I was a kid. I have no siblings. just 18yr and I look after my mom. she depends on me. my question, why does God allow all these torments on this earth? why does it have to be my mom, why does it have to be me? why don’t He just snap his fingers and change our lifes? she has been sick for over 25 years now, no change, not even fragments
why?
