The concept of Karma is such an irrational excuse of reasoning life's mistreatment.
Good things happen to Bad people.
Bad things happen to Good people.
There is no great force maintaining perfect equilibrium.

but I can assure you there's lots of people in much worse situations.
Look on the bright side.
