PM, you need to rustle up support. Of course you're still thinking "if only ... " and "Maybe ... " and the rest of it. Of course you are. You've been brainwashed, sweetie.
You've been subjected to years of mental torture, using the oldest tricks in the book. Those tricks work; that's why oppresors the world over use them. (You're a psychologist, aren't you? You know this stuff!) You can no more swan back into the real world than the guys from Guantanamo. Like them, you need to create a safe space where you can 'be' for some considerable time. And you need support. Ring Womens Aid, honestly, it's not a sign of weakness or anything. It's just phoning a volunteer who has been where you are, and knows hundreds of women who made it through like she did.
What's this crap going on with your work? Obviously they can't do anything while you're pregnant - does that mean there's a fiasco on hold until you return? Is there some possibility your STBX may have undermined you without your knowledge?
How about the furniture thing, too? I can't quite see how you'd take care of a million kids, hold on to a professional position and restore furnishings, but I'm just about ready to believe you are superhuman!! Is this something you'd consider as an alternative to your profession?
Your remark about "fitting" on holiday made me cackle loudly. I'm an incurable traveller, have done some amazing things: but, for all my travelling, I have only ever "fit" once. That was in Spain, a couple of years ago, when I took seven of my nieces & nephews for a walk. Wow, the approval! I could hear the Spanish mommas, poppas, aunties & uncles bellowing approval to one another! Of course, they thought I couldn't understand, heh: "How many? Seven, I thought five? No, it's seven, there are twins! So blond, so pretty, so well behaved. How old d'you think she is? No, she must be older than that, so many childre ..." etc.
Mate, I loved it
Turkey will love you all the more, for NOT being hemmed in by an obstreperous husband! I guarantee it.
Hold fast, you're worth it.
(Shit, why does everything sound like a hair care commercial?!)
