is it in my mind?

Since I found out that I am pregnant I have felt more and more naseated and simply exhausted. I know before I found out I was not feeling all that great. but WOW I wonder if some of it is in my mind. If I didn't know would I just ignore it and go on a lot quicker? I dunno. But i'm totally tired. I took a four hour nap this afternoon and i am still tired. I have a load of paperwork to do for work and I am sitting in the living room blogging. Yeah I'm not getting much done am I :) LOL>

Ahh well.
