Oh, my god my back hurts!

I wanted to go to work, I am not a skipper. However, today it was phisically impossible for me to get out of the bed and dress up for work. My cell phone was in reach, and I could have called in sick. However, I did not want to give up. So I pondered and think of strategies how to lift up my butt and open the door that is two feet away from my bed.
I kept thinking and thinking and thinking while the clock goes tick tuck tick tuck. I opened my eyes and realize that I still have another hour, if I skip my breakfast, to lay down and give myself time to rest and possibly gain the energy to at least sit up.
An hour later, my body was rigid and I came to the realization that I would not make it today. In five minutes later, headlines from daily newspapers and news reports hit my head. "job cuts, recession, unemployment goes up to 7.2 percent."
I got caught up in a thought that I might get fired for this unknown physical problem, which did not mamke any sense to me at all. I started to panic, and even harder I made an effort to get up.
Well, I guess while I was in fear of losing my job, three hours passed by, and I receive a phone call from my boss.
"Ms. Sato, it is 11.46 a.m. and I still do not see you. I am wondering what is happening with you today. Your clients are calling and please call me back as soon as you can."
That was it.
I called in, feeling ashamed and embrassed acting like a college kid who just want to skip his class.
However, later on I remembered what my mentor said one time, when I asked him what if I can't keep my promise to my clients.
He said, " it is not the matter of wether or not you can keep the promises. Things happen. Your car got broken down on the way, you get an emergency phone calls, and you might get sick, but what is more important is how you deal with it after that."
Today, staying in bed, I thought that I should have made a phone call immediately, so that I wouldn't have made any trouble to other co-workers. Yes, I might get sick or might not function well. I have a lot of work and responsiblities that might make me physically fatigued.
However, calling in sick on time is also one of my important responsibilities.
