"Because of the hours I work and commuting I barely see my children."
If it's a long commute, one option might be moving closer to work so you have more family time and more time to think about what to do next with your life. Alternately, try to find a means to use that commute time constructively in a way that will help move you out of the current miserable situation and into something better -- books on tape, hanging on the cell phone with the wife, or even just using that time to think on your priorities and try to dream up some solution.
