Work Overload

I'm on the verge of having a nervous breakdown.  I take over Algebra I tomorrow, meaning I will officially be teaching all of my CT's classes.  Plus, I just found out that lesson plans will now be due on Thursdays for the following week.  So, essentially this means I have two sets of lesson plans to plan for two weeks as I have zero time after school to work on plans.  I was in Myrtle Beach yesterday to present at a conference on "encouragement in education" (supposed to look good on my resume)...well, I'm not feeling very encouraged.  It took me four plus hours to get home because of bad weather.  I have been working on plans nonstop this morning since 10 AM and I'm not even finished with half of the plans for Pre-Algebra.  Making those stupid SMARTBoard lessons takes FOREVER.  Not to mention all the worksheets, handouts, etc.  I don't know how I'm ever possibly going to get all of this done.
