Am I really a teacher??

So this week has been kind of rough at school. I don't know what's gotten into the students but it's been hard to keep them on task and get anything done. I have to admit I haven't been as patient with them as I should be, but I was seriously at the end of my rope! Today during my prep hour I walked into my classroom and it just kind of hit me-I am a TEACHER. And it's not like this is my first week, this is like my 3rd month! How the heck have I been teaching school for 3-almost 4 months already? I can't believe the time has gone by so fast. I think back to a year ago when I had just found out my student teaching placement would be in a 6th grade class and I cried because I thought there was no was I could ever do that. But I did! And it was a great experience. And now I'm 4 months into my first year of teaching. I've made it this far, I'll be able to make it through the rest of the year right????? Or at least until Christmas I hope? Really the only thought that's getting me through this week is, "3 more days of teaching till Thanksgiving." or "one week from now I'll be in relaxing in Idaho with my family, sleeping in, stuffing myself with food, shopping, not grading papers, not teaching how to write using alliteration or whatever...." Anyway, that's my venting session for the week. I can assure you that not every week is like this one, but somehow the bad weeks stick out in my mind more than the good. Thank goodness we're on the home stretch for this week!
