i am skeeered

I don't want to go to school tomorrow! I have not been in a "class" forever. Online is much less intimidating. I am excited to be taught by a teacher and not just myself figuring it out, but not only am I going to be IN a classroom w/ peers (well it is comm. college so probably 19 yr olds) but I am taking bizness math and GEOLOGY!!!!!! I hate science and labs! YIK! I am nervous. I have a lot on my mind right now anyway and I can't seem to get it straight in my head that worry is a waste of time....
