Switching careers? Another degree?

I completed my undergrad in 2000 and I'm at a crossroads right now. My bf is encouraging me to go back to school and complete my teaching certification (I have 2 BAs and can receive certification and licensing in about 6 months). I've spent the last year substituting and trying to find my particular teaching niche, which seems to be high school English.

Here's the problem - I really enjoy teaching, but there are no permanent openings in my area (relocation is not an option), and future openings are looking grim. There are, however, many job openings advertised for LPNs and nursing. I'm thinking of going back for medical assisting, finding permanent employment in the medical field, then continuing my education for either LPN or RN.

Anyone familiar with how elective credits would transfer? Recommended programs (online even)?

I'd be happy in either field, but the bottom line is job security and being able to pay the mortgage. Anyone out there dealt with this? Do I continue on my current teaching path and just hope for an opening? Doesn't it make more sense to pursue a career where I know there are more jobs available?

Where do I go from here?
