is nausea normal?

I suppose this is celebratory news but I just feel rather nauseous. After meeting with my Program of Studies committee today, I have a clear path toward my graduation (avoiding all pitfalls and postponements, of course), which is a really good feeling, in some ways, but not so much, in others. The responsibility of it all is rather overwhelming. It's one thing, for instance, to say that I'll take my comps in the late fall; it's another to look at the calendar and realize that's only 7 or 8 weeks away. I have lots of reading, preparing, composing and outright studying to do - and studying has never been my strong point. That said, I really want to do this - when is more of the issue right now. How can I manage to prepare when I'm filling my days already? The obvious answer is to drop something but I'm not sure what that would be - as I mentioned last month. I'm learning lots from the TA positions; I'm paying my rent with the assistantship; I'm getting lots of valuable experience as president of the graduate student association - although the time and stress involved with that last one would appear to advocate my resignation, I'm hoping I can find a happy medium sometime soon.

Okay, enough of this. I have a busy schedule for the fall but I wanted this. I want to do this study; I want to keep moving ahead; I want to graduate. Worthy goals, all. That means I suck it up, get it done, and do it well. Maybe I should put that over my desk...
