It's A Hard-Knock Life

Another day off to pour over obsessively this grad school thing.
The problem with creative writing is its so subjective; I'm not even sure what is "good" and what isn't, I just know what I can produce and what I can't. Last week my friend Liz was writing a paper on creativity and it got me thinking about the whole process. To create anything is mindboggling; I don't ever plan to have children, so my writings may be as close as I get (as melodramatic as that sounds). I'm sure ya'll are really sick of me talking about these writing samples I have to produce, but it's all that's in my life right now so it's all I can talk about. Sorry.
First I have the statement of purpose, which is supposed to sum up me, my entire background, my writing experience, why I want to study creative writing and what makes me a good canidate. It's the most important part, and I have to say that I'm so stressed about it I almost don't know how to go about doing it. Today I spent half the day staring at what I'd written so far. I think I wrote maybe one new sentence.
Then there are my short stories. I have to submit two stories. The problem is, I have yet to finish one story. I've started plenty of them, I just can't finish them.
Oh no now I'm having a panic attack, doubting my abilities or my desire to study this.
I want to, I know I do...I just don't know how.
AHHHHHH!
I may rip out all my hair.
