I've been writing myself into ruts

When I'm not in school I can't wait to be there, but then I start and am reminded of the precise reason I can never wait for the semester to end. One of my classes is taught by a mountain troll who makes me feel incompetent and insecure with my writing. I'm sticking it out though and I refuse to let her get to me. Despite her mastery of the English language, namely grammar (I make mistakes occasionally, for fucks sake I am human), she will never have it all. I hate to be so petty, but I occasionally look at the picture she posted of herself in her bio (online class, everyone has to post one) and I feel better knowing that, despite her perfect use of language, she is rather unfortunate looking.
