Need some urgent advice, please... Sorry it's an essay, but don't want to drop feed!
I'm 30+2 today. Just had a GP appointment as I have been feeling severely depressed and anxious for some weeks and it's getting unmanagable. I've had 'severe clinical depression' on and off (mostly on, especially in the Winter months) for over 10 years, but came off meds early in 2014 when we started TTC. I kind of expected the depression to kick in again within a few months. Well, it has, been pretty bad and rapidly deteriorating since November. And my midwife has been as much use as a chocolate teapot in terms of offering me additional support, so I've now spoken to the GP.
GP and I agree we'll try to keep me off meds till the baby is here (I get really severe side effects from the meds even when not pregnant - the only medication I get on with is one half decently is one that's not safe in pregnancy. Long story. Suffice it to say that in my case, it's not a good option for medical reasons.)
GP has done an urgent referral to a counsellor and signed me off work for a week to start with, but he said he'll renew it weekly till I feel ready to go back. He's been really supportive, I wish I'd gone to see him sooner.
GP stated prenatal depression in last trimester of pregnancy on the form for work (Fitness for work form) so that I don't have to admit to work that this is an ongoing, long-term thing, which would basically kill my career. I work for a very fast moving, somewhat cut-throat multinational company and in a pretty high-powered job. 12 hour days are the norm, plus early / late conference calls with other time zones.
My boss is not an evil guy, but clueless / insensitive / prejudiced against mental illness. I know this from comments he has made about others over the years. 
So right now I am sitting here in tears because I can't figure out how / what to tell work. Do I call my boss? Do I email him? Do I email HR? Or HR and the boss together? Do I even have to tell boss what it says on the form? Can I phrase things vaguely and just send the form to HR? And what in the world do I say?
And what do I tell my team? I don't want them to know I'm depressed. It's none of their business. I know it's nothing to be ashamed of, but I am a private person and I don't want to discuss my health, mental or physical, at work.
I also have a huge amount of stuff on at work over the next week. Several things are the kind that no-one else knows how to do. My DH says that's their problem, not mine... but I feel hugely guilty about leaving people in the lurch. Can work expect me to do some of this stuff from home while off sick? I suspect not?
Help, please. And sorry this is such an essay.
