Chris, my family is not one you would consider to be "in touch with their feelings." All of us are kind of a caricature of the stoic military man. They were NOT going to ask me how I was doing, and when I eventually brought it up, you could kind of see in their reactions they were thinking "wtf?"
But the funny thing is, that even though it was really hard to open up to them about it, when I did, they were extremely supportive, and usually call once a week or so, "just to check up."
They'll probably be more supportive once you let them know it's ok. You don't really have much to lose by trying.
