Barry, I hear you, I really do. You need to start moving forward. Make some plans, make a life for yourself. Start living. I know it is hard, but the sooner you start planning your path ahead, the easier it will get. Take the focus off of your W, there is nothing to be gained by obsessing about her. She is gone to you and no amount of crying will get her back, no pleading will soften her heart. Take care of yourself, you matter, spend time with the kids, go do stuff together. Lough, walk, talk, smile, LIVE.
If you need to vent, we're right here for you buddy. You are not alone.
