Thanks everyone for your kind replies.
I've been off work yesterday and today but the flare is calming now, thanks. No doubt it will be noted that I've been absent but the fact that all this stress has caused the flare has also been noted by me. And the bloods show it too- lucky I had them at the right time

. I still feel quite stressed about it and it will take me a while to settle down.
What really got me most of all was the timing- hitting me with it all at the end of a difficult term, just having lost my dad. However- it's all over now, so time to move on and accept that some people are just s***s!
I guess I've been lucky with previous heads- especially having read about your experiences. It still makes me angry that there are such bullies- something that made me more determined not to let this one beat me.
I've also learned that another colleague took him to task last week over his treatment of her when she was having health and personal problems. It clearly wasn't his week!
Jenni- no doubt he will try someone else, athough I'm not getting too complacent: I'm still watching my back.
Katheen- your head sounded dreadful!
I'm just watching an interview with the tenor Russell Watson on 'Lorraine'- what he has gone through just puts my work problems in perspective.
Love to you all
