Sorry you had to find us. We all remember those days.
First...and most bluntly: it will take a long time to get past the pain. I don't think any of us ever really "get over it". It just gets smaller and smaller.
Secondly...hard as it is, try to focus on very simple stuff: taking care of your kids, and especially, taking care of yourself. Eat right, exercise some, sleep right.
The hard part: don't allow yourself to focus so much on "the details". Some people report good results by setting aside (only letting themselves) deal with, think about, or talk about affair stuff for a limited amount of time every day, then every other day, then eventually every week. That takes a really disciplined mind; it's not "denial", just a sort of self-saving "compartmentalization" to take back your life from affair talk, painful triggers, and memories.
Some people even find that it helps to come here and share their feelings.
Again...sorry you had to join the club no one wants to belong to.
Chris.
