That's all it can be.  Since the meltdown at work on Tuesday, things have gone from bad to worse.  My manager has promised that I won't have to work around the two attack-dog colleagues for as long as necessary, and has arranged for me to see someone from the behavioural team once a fortnight.  But I've lost over 3 lbs in weight, can't eat and can't sleep.  My blood pressure has always been 'normal'.  Now it's on the borderline between hypertension Stage 1 and Stage 2.  My heart is pounding so hard that it's keeping me awake.  My head is killing me.  At work today, I was on edge the whole time.  Just catching a glimpse of one of the culprits sent me running to hide.  The last time I was like this was 20 years ago, when I was bullied badly at work and ended up being so sick that I wouldn't go out for weeks - and every time I saw a red car (the colour of the bully's car) I'd duck into shop doorways until it had passed.

It's like PTSD.  I can't live like this.
