I don't know about you, but I think a major factor in my anxiety is that I perceive everything to be of the same vital life-or-death importance. Not every decision or occurance--well, hell; hardly any decision or occurance--deserves that kind of gravity. But somewhere, the wires crossed and they've never been uncrossed. A kind--but firm--talking to seems to help, along with dragging out the catalog of past catastrophes-that-weren't, but perhaps for some of us this is a lifelong struggle, a persistent habit.
And, you know, if that's the case (and even if it's not), the greatest gift I can give myself is to stop apologizing for how I was wired, to stop apologizing for being an inconvenience, a burden, square, uncool, unattractive, or any of the other hundreds of things I apologize for on a daily basis.
I'm trying, but I'm trying for me--not for the rest of the world.
