Culture, Attachment and Need

I'm taking a class this week called Home Life Enhancement - a member care class that focuses on a missionary's life within their home: marriage, kids, etc. I'm only on day two, but so far I have thoroughly enjoyed the class.
Today we talked about attachment theory and its implications to people in general and to missionaries in specific. I know psychology can scare many people away with theories and wondering if they're biblical and what-not, but one of the basic concepts of this theory is that we need people. We need to be in community and have people around us who know us and love us. As missionaries, we need to have people from our sending country that if we had to come back for an emergency, we know we could come back to them and even though they may not totally understand everything, they would want to listen.
Whether or not you can wrap your head around the whole theory, the truth is that Christ put us in a body. He did not call us to be separate individuals living for him. I think in our culture we forget this too easily. We think that my pain is my pain alone. We forget that when we suffer, the whole body suffers (1 Cor. 12:26). Whether the body will suffer with us (allowing others to join in our pain through telling them) or because of us (not dealing with the pain and having it manifest itself in other ways) is our choice.
Can we throw off some of our cultural baggage, can we actually admit that we need one another?
