Something happened that reminded me of this post yesterday and I spent most of my evening trying to find it. I eventually did but then fell asleep halfway through reading it so I've just finished reading the whole thread now.
I wanted to post on here and update everyone - all the amazing people who replied with really thoughtful, helpful and caring messages. I wanted to let you know that they helped in more ways than you can imagine, and I wanted to update you on my life.
Reading my posts back now, I realise how detached I sounded, almost as though I was viewing my life from outside of my body, a kind of numbness that enveloped me during that part of my life. I know now it was a coping mechanism. I didn't feel anything during that time except anger, fury. My mum was losing her battle with cancer, and she eventually did that year in June 2017. My dc3 was born three weeks later. We delayed the house move that year - I had a kind of mental health breakdown six months later so very thankful that we stayed put for that year - and developed serious anxiety/depression. It was tough going, between dh and I - as you all know he was already at the end of his tether, and at times he did check out from supporting me and buried himself at work and I was alone in my grief. But only briefly; he always made sure he was around physically if not emotionally at times, and I totally understand how difficult it will have been for him. But we've got through it, together. That's what counts.
Looking back, I realise I was taking on a lot of the family anger - old anger, new anger, old learnt habits and changing family dynamics with mums terminal cancer. The family dynamics changed further after we lost mum. Having already lost dad years before that, it's now just us siblings and it's down to individual relationships. Essentially , I have good relationships with those I have a bond with and NC with those I don't and I am happy with the way things are. I have also learnt how to place firm boundaries not only with my own family but also dhs, and there is no more toxic shit from the in laws.
The baby I was pregnant with in my original post is now 4 years old and she is the most beautiful and happy little thing on earth and I love her with all my being! Alongside my other dc of course 
We moved house in 2018 and it's beautiful - a proper beautiful family home and we couldn't be happier here. We bake, we cook together, we do movie nights, we fight too of course
but we have our own family days now on Saturdays and our own traditions. Dh still works too much and hes still a grumpy sod at times-the dc still sometimes have the odd crazy afternoon with a stray marker pen/paintbrush
but this is my own precious little world, and my own precious family who I adore beyond measure.
Life is not perfect but it's a million miles from my original post, and I guess I just hoped some of the really lovely posters would see my update and I'd get to say thank you
