I am such a freaking retard.
Next time I do something as dumb as this again, please follow the following procedure:
Step one: Stop hating myself
Step two: Stop wallowing in my loss
Step three: Repeatedly smack my head against the desk until I lose consciousness
Step four: Ideally lose all memory of doing said stupid thing and proceed to start again on work as if the last four hours hadn't happened
Step five: NEVER DO SOMETHING DUMB LIKE THIS EVER AGAIN
