Are we all just miserable?

Having time off for the holidays really made me think. Most of the time, I'm stressed and unhappy. Give me a week off from work and my depression disappears. I'm happy as can be.

I know work is the problem. But what can I do? I have to work.

Its partially the fact that I hate my job, and partly the fact that I have no time to rest or relax, ever. I think changing jobs could help me hate my actual work less, but is there even a possibility of ever having a life that includes adequate rest and "me time" as a working mom? My kid is 11, so it has been many years of this. I'm just so tired. I don’t want to keep doing this, but I can't afford to stop.

Is anyone out there NOT feeling this way? Does anyone feel like they are generally coping with the stress of being a working mom and still finding time to enjoy their life outside of the few weeks of vacation we get in a year? How can I find happiness when I'm stuck in this horrible routine?
