I'm half way through my pregnancy and feeling burnt out. I've taken a few days here and there with exhaustion and sickness, but I don't know how much longer I can go on like this. There are staffing issues in my department and I'm the HOD, so left holding the can. Deadlines keep piling in. I can't switch off. I can't stop crying at home. I can't sleep, partly due to being physically uncomfortable and partly because I can't stop worrying about work. I worry I'm depressed again (have been depressed before, but managed to only take a few days off and drudge on at work through it). I've booked a dr's appointment for next week. I've also prepared a letter for my head explaining how I'm feeling but not sure if 1. I should send it and 2. if I do, when is the best time? The day of my doc's appointment? Before? After? My colleagues are pretty nice, so I'd feel guilty if I'm signed off for a couple of weeks, but at the same time, I honestly don't know how I'm going to carry on if I'm not. The idea of being signed off worries me too in that I wouldn't know how to set work for more than 2 days in a row! My SLT are nice enough, but not particularly aware of the extra stresses I'm under that other HODs in the school are due to staffing and also with the added pressure of pregnancy. Any advice would be greatly appreciated.
