Feeling Inadequate

On Thursday, I defended my master's project.  This had been a project that I'd been working on for over a year.  A project that involved a paper that had gone through three rounds of edits.  A project that was pushed back time and again because of my professor's vacations and lack of responses.  A defense that had been rescheduled because of my adviser's father's illness. 

That brings you pretty much up to speed.  Now, my oral examination went fine and I received the grade of a pass with minor revision.  My adviser told me that the main thing I needed to fix was to change some of the language to make it not a causal relationship.  Okay.  I can do that.  She also said that I needed to make the writing umm... better.  Okay, I guess I can try to figure that out.  But don't you think that she might have said something during one of the three rounds of edits?  Or maybe, during the month and half long period between my "final" edit and the defense.

Then, yesterday, I received an email stating that I needed to make the paper writing style more academic.  What the hell does that mean?  Am I using too many colloquisms?  Is it not written at a high enough level?  Is my writing style not advanced enough?  Is this throughout the paper or concentrated in sections?  Are there specific parts that are lacking?  Sounds like criticism that I can go off.  But nope, I just receive I need to make it more "academic."  Well, I'm sorry, but I have never received a score lower than a B on a paper.  Ever.  So, if my writing style isn't academic enough, then mightn't one of my professors in undergrad have given me a lower grade or asked me to change?  Or, even more likely, one of my grad school professors.  But no, from them, I receive critiques like this is the best paper in the grad or you missed two points out of 100.  So, now, I feel as if everything I've done is a lie.  As if, I was just passed along.  Maybe it's the opposite, maybe instead of being the top of my classes(with a 3.79 GPA for Grad school), I'm really at the bottom.  Maybe I'm just not good enough.
