Like a lump in the throat but in the stomach?

Change a thing I have never been a fan of, yet it always seems to find me. I should be ecstatic right now I am almost done with school, in a few months I will be a graduate. For some reason I have this unsettling feeling deep inside me. It's almost like a fear of moving forward, I can't honestly explain it I'm happy but horrified at the same time. what if I forget everything I know, what if I come off as stupid even though I have achieved almost perfect marks in all of my classes. Let me give you an example of why this has come to me lately, we were in class one night just messing around and some how the topic got into medical terminology and I felt less than I ever have. Perhaps I should add some clarity so you understand why I am upset our first term we had terminology and I thought a good teacher. what did I know it was my first term and I was new and nervous. anyway after that term he was let go and when we were talking about the medical terms and breaking down words, the things they were talking about things were some that we as a class were never taught. It frustrates me because it seems in my school people don't get the same training or learning each term. With different teachers coming and going it's hard to get a grasp on anything. I don't like feeling this way I really don't, but what can I do even if I try and bone up on my studying is that enough? or will the lack of proper technique hurt me in the future? So many questions sit in my head it's hard to ask them all especially when I don't know if I want to know the answers to some of them. I just wish I could take this uncomfortable feeling that I feel away since like I said I should be happy but it's fading quickly what with a very hard test to become fully registered looming around the corner. I guess I'll just have to press on and hope that I retained something and wont look foolish. I know it may seem like idle venting but this pops in and out of my head and brings me to a place I really don't want to be.

One night and one more time I hope it all stays in my old brain.
