Thanks guys!!
Frank, I think you are very right. I do miss volunteering. When I was in San Diego, I had a food share program (on MCRD) that I did once a month. Since being back here in IL, so much of my focus has been on our situation-trying to rebuild after our tenant nightmare-that it has left little room for "doing good".
I have to say I do miss being around the military community, especially the Marine Corps. Here where I live now there is a minute presence and we're spread out. Ellen (Elmo) had a good point, I don't have very much time left before I start my new job so I suppose my focus is definitely where it needs to be right now.
As for loneliness, it would be there even if I was volunteering...you just can't deny that there is an emptiness when your husband is gone. At the end of the day, when all is quiet and you don't have his arms around you...is when it creeps up.
