Why I worry about things I can't control

My stomach and head have been doing a number on me.

First of all, I have been super stressed out about school, not just school stuff that is happening this semester, but much more and it isn't fun. Here is the break down:

1. I have to take my Generalist exam in December and pass it mind you. I am really nervous because of the amount of content. I am also nervous about how the test is set up, they give you these situation questions with four answer choices. The problem is that the four choices all sound great! GAAAHH, I can't stand it.
2. I have a lot of classes this semester, 6 classes, 60 hours of field work ( in two separate schools), and so many books that I had to create a filing system to manage them all.
3. I'm getting married in the not to distant future, my future husband and I have yet to set a date or even talk about the wedding.
4. Last but not least, I am a terrible procrastinator. I can't help it, I know I have three assignments due and yet I feel the need to play hours of tetris. I need an intervention

I have taken steps to quell all of my self induced sickness, I have started using my planner to... wait for it......oh you will never guess.....Plan My Day! Usually when putting stuff in a planner it consisted of what is due and some important dates. Now i have a daily play by play of what I will do and when I will do it. I didn't follow it yesterday, which was a mistake because I got to freak about it when I got to school, but it did work out. I just had to put those extra stressful moments into my day.

Why does the title say "things I can't control" when you really are in control of them, you might ask.
That had to do with me meeting with my advisor and loosing sleep the night before. I freaked myself out because I had a meeting to talk about graduation and I thought he was going to tell me I missed a huge chunk of classes and I would have to stay another year. GOSH I WAS STRESSED! It ended up working out though because I am graduating this may and I will pass that certification exam, and will get a job. Until then I will just have to do my best.
