Bad Mood

This morning I woke up before my alarm went off, and just laid in bed thinking. I was able to sleep in today since I needed to take Y to school. My mood was just fine. After dropping her off, and heading into work I could feel myself tense up. I walk through the office door and almost immediately I'm in a bad mood. I go to my desk, get organized, and start working not really talking to anyone. When I am in a bad mood I tend to stay by myself. I don't want to effect everyone else. I'm usually extra quiet, so what I can't understand is, why can't I just be left alone then!?! I'm not going up to people saying "I'm in a bad mood, ask me why" rather I sit at my desk doing my job, something I am paid to do.
Lately I've noticed after 2 full days in the office, I am in a bad mood. Which doesn't really work since I have to be here a total of 4 days a week. Since we fired the last office assistant I've been working 5 days. Maybe that is why I'm in an extra bad mood today. I want to go back home crawl into bed and be left alone. This place stresses me out. The main part of my job can be done in 2 days, and it usually is, so the last 2 are filled with office b.s. from other employee's, and right now I am helping with the regular office stuff since we are short staffed.
I've made it very clear to my boss that I probably won't be coming back after the baby is born, and if I do, we have to discuss a new contract between him and I. 4 days can't happen. I'm doing everything I can to help me go further part-time. I understand it's a lot to ask of him, which is why I didn't really ask him at all. He wanted to know why I wanted to not come back, so I told him the hours would be to much, and honestly I don't want my other title. Now I like to plan for the worst, so I don't really think he's going to let me go to 2 days a week, and give me the few other things I want. My plan has been to start looking for other part-time work, and finally get my resume together! If I'm smart $$ wise I can pull this off. Besides everyone knows when I put my mind to it, I make it happen!
In order to stay where I currently am, I need 2 days a week, or no days. This place is to full of b.s. for me to deal with.
When I get off I'm headed home to take a nap, but I'm not a good napper. Here's to trying!
