Lisa, Checking in to see if your h was found. It sounds like he's hit a rough pocket of depression and he should be on meds and seeing a therapist. Unfortuantely, when they begin to feel a bit better, they tend to cease seeing the therapist. I do hope that someone can convince him to go back into therapy. He needs it now more than ever.
About employment, w/his degree and experience he shouldn't have a problem w/employment. When he's in a better frame of mind, suggest that he look at some of the "contracting" positions that private contractors may have working for the Federal Government. There should be plenty of private contractors in your area. They pay well and have good benefits in most cases. It's a stepping stone to other positions.
Lisa, I'm so sorry that this has happened and I do hope and pray that he's found safe and sound. I'm sending warm thoughts your way this morning. Please let us know how you and the family are doing.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
