Good luck at the interview. While I understand how stressful getting another job started is, it will be worth it when you land the new job. Try to focus on the positive! Sometimes our depression makes us think that this is our "last chance" but, many times, failures aren't last chances, rather, they lead us to other successes. Picture yourself in your new job!!! Assume you will get it but if you don't--assess why you didn't. I am crossing my fingers for you!!
