Burnout

I've been at my current school for half a year now. I cam from a pretty challenging school, heading up a shortage option subject, with the hope of getting more support here. So far, I have endured, extremely poor behaviour from students, ineffective support from SLT, two thefts from my classroom with little consequences....on top of that, the other teacher in my department is leaving soon (they've had enough) and there's no replacement in the pipeline, we're still recruiting for a technician, we have an Ofsted Inspection due soon so extra pressure.....

I've reached the point where my partner has noticed the change in me, I feel constantly tired, fatigued, aches and pains and just generally "dead" during the school day.

Is it time for a change? Sign off sick for a while? New position, considering it's been less than a year?
