You know. The most important thing is to remember its a process. And that its not forever or fatal, even if you have anxiety/depression issues.
If you obey the no-contact rule from day one, it takes only about two weeks to get through the worst of it. And its a lot easier if you excercise, sleep 9 hours a night and eat frequently.
If you keep talking to him it astronomically increases the time of recovery even if you eventually follow the no-contact rule.
So remember focus on process. Its not something that you can just turn off like a light switch. ITs more like the Flu you jhave to endure it knowing it will be over soon and do some small things to be easier.
Now if you don't follow the no-contact rule . . well you deserve your misery
