Not to sound too much like a student....but can I have another holiday please?

Ok...I have reached the mid placement blues. Its not that the school or department isnt great or that there is anything wrong with the placement at all....I am just so tired. I thought that having a week long holiday in the middle of this placement would help but I think it has made things worse. Getting back up to speed with the demands of teaching has almost killed me today. The lessons went well but I can barely keep my eyes open to plan tomorrow's. Stupid question but does anyone have any tips for dealing with the exhaustion?

I am all for hard work but the double requirement of school and university work is seriously draining. It seems ridiculous that all of the university tasks are left until placement. Oh well...that's enough procrastinating...back to planning!
