Excuse the vulgarity

My writing doesn’t usually include inappropriate slurs and crude language, but I’ve been extremely frustrated with..everything lately. My mother’s tunnel vision about society, immature girls at school with basketball bellies, my own stubborn tendencies..Everything is just so exaggerated and overwhelming right now. And half of the problems I allow into my mind aren’t even my own. They just rot in a corner and fester all of this hate that I shouldn’t possess toward situations that don’t concern me. 

My problem? I care too much about others. But why is that such a bad thing?
