Moving forward after the death of loved one

What can I do to overcome the sadness that has overtaken me since the death of my husband? How do I step forward into the next phase of my life? He battled a number of challenging health problems during the last two years of his life. As a result, my entire identity became wrapped up in caring for him and meeting his needs. Now that the struggle is over, I feel empty and lost as well as grieved. I honestly don't know where to turn or what to do next. Can you help me?
