Guess What?
We're not getting any younger, it's literally all downhill after this. And, surprise...your life isn't going to change/improve unless YOU do something (besides complain) about it. People have been mean/shitty/disagreeable/dramatic/ugly/biased/non-logical etc. since the beginning of time and it isn't going to change anytime soon, and neither are you unless you do something about it. Only you can make yourself happy and make the decision to be happy, trust me.
