I just found your thread and want to chime in with the support of everyone else.
I am working intensely hard on controlling and changing my thoughts. I will look at THE WORK that you linked to as soon as I post this.
My partner did a sudden walk away, so I am with you 100% on the total surprise and devastation.
Some of the best advice here for the early days: put your focus on you and the kids. YOU are the most important thing right now. And taking care of the kids, of course.
I see in your note that running is an activity you like. I'm sorry you have been too ill to do that. But think about trying it as soon as you can, or walking as soon as you are ready.
I found running to be the best stress relief. I read a lot about how our anxiety is created and stored in the amygdala, the primitive part of our brain responsible for "fight or flight." So running gave my little primitive brain what it wanted: FLIGHT!! The more I run, the calmer I am.
I also do a lot of positive self talk: you can do it; you can let go of the anxiety; everyone is here for you, etc., etc.
Hang in there. We're all here for you.
