Hi Hoser! Welcome to DB. I'm sorry you find the need to be here but you will find that you have come to the best place to help you through what is going to be a very challenging period in your life.
Reading through your post, it would seem that your focus is appropriately placed where it needs to be at the moment, namely you. You are going to need to take good care of yourself; sleep, eat, exercise and get a life independent of your WAS.
Something you need to do right away is get yourself a copy of Divorce Remedy or Divorce Busters and get to work reading up on what may be the best chance you have to restore your marriage. It is important for you to understand however, that restoration of your marriage may never happen. But, if you do this right, you will come out of this a better person than when you started.
Also, the things you described as your initial reaction to your wife's pronouncement is typical. But now that you are over the initial shock it is important that you stop all pursuit. You will find that the more you plead, beg or otherwise pressure your wife to come back, the farther away you will push her. So, your GAL (get a life) is going to be very important to your efforts.
One of the things that you should also do is think about the things your W has said were problems in your marriage before she decided to leave. These are the things that you can focus on with 180's that will make you a better, more attractive person.
Enough for now. Keep posting and you will eventually come of moderation. Others will come along to offer guidance and support in short order.
Hang in there. We're here to help in anyway we can.
