Anxiety Worse at Work?

I've discovered that lately, my anxiety is worse at work. In the morning my boyfriend and I are busy getting ready for work, taking care of dishes, cat, etc. He leaves about 15 minutes before I do. On the way to work, I'm listening to the radio. Soon as I get here, it's like even though I'm busy, for whatever reason, I'm more tuned into it. There's over 450 people in my building but only 5 including me in our area, and usually only 2 of those at any given time. I don't know why but I am tuned into stomach, how my head feels, if I'm feeling tired, etc. Maybe because I'm at a computer all day? I do take breaks but I've even noticed how my stomach will randomly feel uneasy, then I start feeling warm in my upper body, then kinda sweaty, then it all goes away within a couple minutes. It's really weird.
