Unhappy

I am currently unhappy with my work. I have been for quite some time now and am just starting to realize that there is little I can do about it for quite awhile longer. I need to get more experience in my field (aka this job) before I can go looking for other work. I don't know if it is this specific job that is upsetting me at the moment or just the fact that I have to work in general - or perhaps that I am not working in something I really love. I would love to go back to school full-time for photography but then I would have wasted the last 5 or 6 years getting where I am now, night courses will have to do for now. I do like being an engineer, don't get me wrong, and perhaps I just haven't found the right position in this field yet in which case I need to stick it out a little longer here to get enough experience to land a better job somewhere else. I know I am not the only junior here who feels this way as we are all underpaid and overworked - in a funny way, the fact that others are suffering here helps it be okay that I am too.
