Well, I can somewhat emphasize what you're going through, Beth. About a year ago, my dad retired from a local fire department after 25 years, but was still able to find part-time work that was closer to home. Well, he had to take some sort of stupid aptitude test that he failed, so he then got suspended from his part-time job. I gave him the same advice then as I'll give to you now (hopefully it won't fall on deaf ears like it did with him): "Every person is born with different interests, and this is a good thing, because that means that, when looking for a job, nobody is relegated to limiting themselves to just one interest. Think of all the things that interest you and see if thjere's a job nearby that lets you use that interest as a way of helping others and yourself". Here's an example. There's a bazillion book/record stores in my area, and those are things that interest me, so those are the kinds of jobs I would want to pursue. My mom hates this attitude of mine, but that's my #1 priority in finding a job: it *has* to be something that is of interest to me.
I hope this helps, somewhat; if all else fails, you could always go back to your tap-dancing studio!
