What am I doing wrong?

For about the last four to six months I have been passively looking for a better job and have yet to find any success. My career aspiration is fairly broad with me trying to find anything that I am remotely qualified (4 year Customer Service, 4 years Event Volunteering, 3 years Video Games writing/cover) but I have not only not had any success finding a better or more interesting job, I haven't even been contact for an interview or even a talk over the phone.

I am constantly wondering what am I doing wrong. Is my resume format incorrect? Am I not vocal enough with my hunting? Are companies really that bias when hiring that they only look for one specific word and I'm missing that? There are so many questions I have and it's really getting frustrating.

I currently work, but I can't see myself working at the same place for very much longer. I have given them the last four years of my life and the return on that investment hasn't amounted to much. I get passed on every promotion even though I have a great work ethic: always looked upon to help others.

Since I have such a great work ethic, able to finish tasks quickly and efficiently, has that actually put in a disadvantage. Since I can handle a greater workload that others, it just means that they can keep me in the same role and not worry about others because I'll cover for them. But it's frustrating and I hate it.

I was always told, if you don't like what you're doing, then don't do it. That might work in certain facets of life, but not work. You can't just quit a job if you're not in a position where you can say 'fuck it' and take some time off. I live alone and in an expensive city; if I quit, I might as well just move back to Ottawa and my mother's basement, which I honestly do not want.

If only I knew what people were looking for, then I would do just that. I am so qualified, but there is just something about me that is not appealing enough when they skim through my resume/cv. Even with experience, finding a better job is no easy feat.
