Yes, so right - can you do the education while doing your job hunt? Do you have access to a less economically depressed area?Nancynobullets: Find a way into higher education that will gain you qualifications. Hopefully these qualifications would give you the chance at a career that allows you to ride that creativity. Since it doesn't sound like you have other formal qualifications this might be hard for you. Going to a lesser college will likely leave you surrounded by those who care less about the subject than you do, as well as being frustratingly immature. My older sister is going through this process right now.
The one thing missing from your amazing list of job search strategies, Gloriana, is hitting up friends and family. Do they all know that you're looking, exactly what you're looking for, and committed to keep an eye out for you? Every single job I've gotten has been through a connection, and not to sound cocky, but I do have the credentials (degrees, GPAs, experience, etc.).
What about gaining experience while you're hunting via volunteering? Skills like publicity, social marketing strategy (you're good at the web and writing, so I could see you in communications -- that's a field and you could take classes for it at a community college), outreach (particularly for non-profits). I wonder if something like communications and outreach for a non-profit could be fun/satisfying. You'd get to work on a cause too. And you're a fantastic/clear writer.
Oh, oh - counseling? Volunteering for a rape crisis center or hotlines? You'd get more social connections that way or get hired by the place you're volunteering at? I know you're a skilled counselor.
Counseling and writing are marketable skills, Ms. not-so-unskilled-by-corporate-America-standards
And maybe we're INFJs, but we're not aimless. Most (from what I read) want to make a positive difference in the lives of others; live an honest, authentic and sincere life; are hardworking; and put that "J" to darn good use in organizing things (marketable trait!) Not dissing P here at all -- I need a bit of Pness in my life. Heh.
