Hard to do for someone who over-analyzes EVERYTHING!! But it's important to get this straight in your head. You can move past the surface and try to understand the deeper workings of someone else's actions when you take yourself out of the equation.
"There are three solutions to every problem: accept it, change it, or leave it. If you can't accept it, change it. If you can't change it, leave it." And for pity's sake, please stop COMPLAINING about it like a victim!
