I wonder how your feelings compare to those of someone I know who left his
girlfriend and alienated his friends in favor of a fleeting opportunity in a
tragically short-lived line of work at an intensely political organization.
When his job and all jobs like it were inexorably eliminated, he spent many
intensely nervewracking months attempting to find a modicum of success
elsewhere within this organization but ultimately failed, all against the
backdrop of a rapidly deteriorating economy, which he could barely see because
he was so close to the carnage. He spent the following months in a listless
stupor, making no personal or professional strides at all, sinking deeper into
a sense of certainty that the ultimate, no-of-all-nothing mediocrity had
finally caught up with him.

Anyway, he seems to be doing OK now. Hang in there; the future starts today.
