Feeling Bad

I was driving to work this morning and I got an overwhelming feeling of guilt and unhappiness. I immediately started to cry. Sitting in rush hour traffic, balling my eyes out. I couldn't even control it, the water works were on and they wouldn't stop. But why?
I think this has been building up for weeks, maybe even months. I seriously hate my job which is effecting my everyday life at this point. I am unhappy, miserable even, for the eight hours a day I sit at my desk. I feel bad every time I drop my son off at daycare because I could be spending my day with him, and even though he doesn't know what I am talking about half the time, he would be completely more enjoyable than the people I currently work with.
I hate that it has come to this. I hate that I don't like the environment I work in. I hate that I don't like the people. And I hate that I can't change it. You can't change other people. You can't change Corporate America. I can't do anything but work and try to find another job. I can't quit, I really can't. As much as my emotional stability and health are teetering on the edge of a fucking cliff, I have to have that paycheck. That stupid fucking paycheck controls me.
So I cried this morning. I let it all out on my way to the fucking job that I hate. And before I walked into that office I made sure my face looked fine, because at the end of the day, I don't really want them to know how much they all have control over me.
