First, I'm sorry to hear about your mother.
Second, I am VERY SURPRISED that you couldn't find a job. Not at you personally, but that there are none to be had in Ohio. When your Mom gets better, you all need to move down here to MD. We have plenty of jobs for you lol. A lot of teachers are at retiring age, so spaces are here for the taking.
Outside of that, to your main question, you could try day care. If you have a degree in Early Childhood. Other teacher degree jobs:
-tutoring center (Sylvan's or something like that)
-teachercare.com (independent teaching)
-Nanny (you can command more money since you'll actually be teaching the children)
-Do a search on monster or career builder. You'd be surprised what comes up under education
Hope that helps. Just keep your head up, something WILL come through. Maybe your unsuccessful searches were to keep you in Ohio for your Mom's benefit. Never know what the Plans are
