Lost, Miserable, and Hopeless

I'm in a process of searching.  For what?  It's rather vague.  I know that I'm not reaching my potential and that I need to move on and out of what I've been doing, especially in the realm of work.  Unlike many others, I have not the capacity to separate my work life from other aspects of my life.  For me to be fulfilled, my work must fulfill me, otherwise I will keep trying to escape my own life.  I am an artist and as such, I cannot ever seem to turn that self-identification off.  This creates a great dilemma for me because I'm keenly aware of the lack of talent and skill I'm currently employing at my job.  While it's been something that has earned me money for essentials, it was always meant to be a temporary step between here and somewhere else.  Unfortunately, 5 years later, here I am, still doing the same thing in the same town and with very little to show for it.  I'm burnt out.  I've been burnt out before, but this time it's even more serious.  This time I have a push and pull need to dive most destructively into the creative processes that will actually lead to a sense of personal fulfillment.  Rational thinking would tell me to be patient and ride it out until an opportunity for a better kind of job comes along.  Emotionally, possibly intuitively, I'm deeply compelled to up and quit, despite the shite economy, and take a gamble on my talents and true passions.  Can I really take another day, another month or six of a job, that while meaningful in it's own right, no longer brings me much joy, a job that acts as a constant irritant reminding me of my underachievements?  I'm finding that rather than letting me relax about basic needs being covered, my job leaves me emotionally and physically drained.  I have very little energy left for pursuing my creative aspirations.  Not only that, it may pay the bills, but it can't sustain certain things like music lessons, supplies, and other such things which I consider necessary to my success as an artist.  Perhaps, I'm just making a bad excuse here, so that I can cop out of just doing something, but I am doing something, and from where I stand, it's not enough.  I need more money and more time and more energy to dedicate to my creative pursuits or at least a job that doesn't suck my creative resources dry.  I've spent enough of the past 5 years sucking it up and making it work, now it's time to make it change.  I will not be doing the same thing in a year or two, I will be doing something far more exciting and personally fulfilling.  Personal fulfillment does not mean that what I do is all about me, on the contrary, I couldn't be fulfilled unless I knew that what I was doing would be to the benefit of others.  I know I'm not the only one in the world who is struggling with these dilemmas.  I know that it's as much a symptom of our imaginatively-challenged society as it is a personal issue.  That said, I'm desperately hoping to gain some practical sense of direction out of my sticky situation, and very soon.  Otherwise, I am ever more liable to make rash decisions.  Maybe that's just what I need....
