There sure as hell is such a thing as "unemployed".
and unemployable because you're over-educated for the position. Especially today, when most applications are online, so you cannot express your desire, need to be loyal for a period of time you'd commit to. It's been happening to me all summer. Yes, I'd work in supermarket, I've done it before. I need the benefits and would need the second job for at least 18 months-2 years, AFTER I find a full-time teaching position. But now I've 3 BA's and a MS, so can't get part-time hire, at least so far.
have you though about tutoring? I don't know what grades you taught or what your expertise is in, but for example you could find work through:
1) searching the part-time and gigs section of your local craigslists
2) posting flyers with your cell # around local colleges / community colleges
3) posting flyers at local community centers / continiung education centers
you can also search for forums local to your city and see if they will let you post your credentials and such on their site.
