I've just come across your post. It seems many of us have been through very similar including myself.
You are doing wonderfully considering that your life only changed recently.
I'm a year in now and in someways I've made great progress but other ways I've still a long way to go.
A little advice is , keep talking , if your friends or family are supportive keep leaning on them. It's incredibly lonely having all the thoughts if you don't share them. Keep a diary of your feelings, good, bad, sad, how your day went or how you are or aren't coping, this is very therapeutic and particularly good to clear your mind when it's the middle of the night or you are feeling too low to pop in to a friend for company,
Cry and cry again if you feel it, let it out, a year later and I find the tears still come but I let them.. it's natural,
Another great idea is look on amazon at break up books!
I got a fantastic book called the break up bible by Rachel.A.Sussman.
It helps to understand your feelings in ways you'd never think of. Read the reviews. I really think this book helped me.
Thankyou those that have written divorce advice, I've noted down some of your ideas
