Stupid, stupid, stupid!

Why do I do things that I know are counterproductive? What the hell is wrong with this picture? I knew that things would be fine, I just HAD to have proof, and now I feel like the biggest idiot on the planet! I'm disappointed in myself. For being such a "smart person," I sure do dumb things on occasion. I don't have to worry about someone else being the death of me; I manage to do that all by myself.
