Why?

why is it that everything is handed to me to do? why can’t people carry their own load? and why is it the harder I work and the less others work the less I am paid and the more they are paid? and why is it everyone around me is so negative? I use to be a positive person…maybe life just changes you, and makes you into something you wish you weren’t.I’m just so tired, I can’t be expected to hold everything together for everyone else when I can’t even hold myself together anymore.What am I suppose to do? I miss my jesus which equals my peace,joy,and happiness.
