It doesn't FEEL like it is great because you are in limbo land and that never is a good place to be. You have to decided for yourself how long you will stay in limbo. Some try to advise you just be done with it and move on and make them feel the loss. There is merit in that, but you have to be in a place where you are willing to do it and willing to do it for the right reasons.
In the meantime, continue to DB. I wish I had a magic formula on how to concentrate on work. But I never cracked that code. Some days were better than others for me, so when you are having a good day, make it productive.
