You are all so kind, it is so liberating to tell people the truth sometimes, which I would never do in IRL where I present as capable of handling anything and a real "coper".
Thank you for worrying about me pidj, chasing, pass. Appreciate pikz's wine a lot. BPLP would be good to see you if crazy scheduling allows, am conscious you return to work soon. Maybe once the dust has settled there? Am sometimes your way for work purposes. Your messages made me cry - in a good way. I asked for a slap, but a hug is what I needed. 
I do need more support. I also have to allow myself to be supported, which I am not very good at. After posting that post, I cried down the phone to my mum, got my pity-party out of my system, formulated a plan, executed the plan, DC obviously got the memo about the plan, and are sleeping, finally. Also made lists of more plans to be implemented. My default coping mechanism. Feel a million times better now am not literally waging a war on two fronts aka trying to get two completely untired children long story, but Wednesdays are fucking badly organised to bed on my own.
I've decided to come off the pill which I don't think has helped and contraception is not actually needed and accept that DH is who he is, my responsibilities are what they are, I chose this life, this set-up, this state of affairs WRT breadwinning and being a mum, I wouldn't want not to be "in charge" of the DC and so I have to take the good and bad of that, I am going to specifically delegate what I can elsewhere, and otherwise make plans to make it all a bit easier.
to you all, you vipers
