Hi JRuss, just dropping by to give you some encouragement, my W and sitch are surprisingly similar.
All I can say is do the work like the others suggest - it's the only thing that will stop you crippling yourself in self pity. I now look and feel better about myself than in years - my sitch however had not progressed much. It's a long road.
Take care
