Sharing hard things

One of the things that breaks my heart the most is how Christians interact with each other. Christians feel the need to hide behind fake smiles with each other. I think we feel that they will judge us or not see us in the same light. Sometimes that thought is accurate. Sometimes it's not. But we are the children of God! Shouldn't we be able to tell our brothers and sisters anything? What if we really shared struggles and hard things. Even our happiest times we don't necessarily want to share.  We need to be building those relationships so that we feel comfortable sharing.
