I know it's easier said than done, but you were in such a good mood the other day after you interviewed for the job. I think you should look forward & stop looking in your rearview mirror. I, too, have made very stupid decisions in the past. While I still cringe when I think of them I don't let them immobilize me & affect my stability today. If you get this new job, you'll have to remain stable to continue working. Keep your eyes on the prize.
