It doesn't seem foolish, we are all going through the same roller coaster. Like I said, I was like that for weeks. That's when discovery of OM made me connect all the pieces and find some peace with myself that it wasn't all my fault. I think your thoughts are totally normal at this stage.
Also, I haven't done any of the 40 day challenge. My W will not talk to me outside of counselling (mediation) and even in there, it is only about separation logistics. Hopefully at some point I can start doing it.
