Actually Finding a Job

I have been accused of being a little "ranty" in my last post.  Well, in fairness, I was very ranty and intentionally so as that was how I felt at the time.  Now I am more concentrated on worrying about getting a new job than the reasoning behind the loss of the original one.
Nigh on every single job I see online is advertised through an agency, and once you get down to the nitty-gritty of it all there isn't actually a real job at the end of it (or it has mysteriously already been filled, despite the advert only being posted that morning).  I have completed several applications directly for jobs that not only fill me with interest and enthusiasm, but seem to fit precisely to my skills and attributes, only to have no response at all, not even a rejection email.
Unless I feel so little self worth as to start applying for jobs which a monkey could do, or joining the ranks of Eurostar call centre staff, it seems like there is so little out there for someone like me who is, ultimately, completely unqualified.
In hindsight I really should have done a different degree, like teaching for example, or physiotherapy.  I would then be qualified to be an actual teacher, or an actual physiotherapist.  Rather than my very enjoyable Film & Television Studies degree which qualifies me to be absolutely nothing.  It doesn't even qualify me to be a film or television critic, because they want people with a journalism degree for those jobs.  I really wish I had paid more attention in the 'careers' lessons at school and college, but I doubt they told us anything useful like that; if my likes and dislikes at age 15 can tell anyone what career I should plan for, then I take my hat off to them.
So, with several years of customer service experience, management experience (albeit with small seasonal teams) and a fluent foreign language, I am struggling to find anything much out there that isn't either depressingly badly paid or requires an extra experience that I don't have - like online marketing, or web design.  I don't think yell.com's web-builder for small businesses counts as web design.
I have a job interview this week, for a job that seems to fit and they obviously like my CV enough to think that I am not completely unsuited for the job. But in a month of appliations this is the first interview, and as the days tick away leading up to my imminent unemployment, my inbox is not filling up with offers as I had hoped it would.
So I keep plugging away with the applications, in the hope that someone will see me for the wonderful person that I am and the amazing skills and benefits that I could bring to their company.  And still keeping my fingers crossed for that lottery win...
