That's difficult to answer because we were kids who trusted the wrong individuals. Some of us have grown up distrustful and fearful of being vulnerable again.
For must of us, safe people are available. We're afraid to approach them and focus on all the harsh, judgmental things they will say to us. And that might happen.
To heal means to encounter risks. Look at the people in your circle at work or church or wherever you're with others. Then trust your instincts. That's the only way I know how to say it. We were violated and victimized as children, and we may be afraid. Despite that, don't we sense those who deserve our trust? Those who care? Whom we can trust?
I believe that opening up to others is an absolute in healing, and I also point out that the first steps are the most difficult and painful. You know the people who listen—really listen when you talk. You also know they don't spread gossip or speak ill of others. Trust them.
