It's normal to feel lost and normal to be all over the place emotionally.
You seriously should call and get a DBusting Coach. I would ask for Chuck. They are the experts. Money well spent. They are TRAINED in these types of things. Why would you not get help from a coach when your marriage is teetering on the brink?
When a person has money issues, they go to a money expert. When a person has a problem with their vehicle they can't fix, they go to a trained mechanic.
No different here. Get a coach. They can get you centered and on the right path. You won't be sorry.
