During my worst moments saying the Lord's Prayer over & over helped me to cope & eventually eased the trauma of learning what we all have learned here. Spiritual strength is important in this battle.
As for your family, don't worry. Try to think of pleasant topics of conversation, scatter seeds when you can. Some will germinate, some will not. Everyone is waking up at their own rate.
I had a "crazy" friend always sending conspiracy emails after 9/11. Most of it I barely glanced at. I couldn't conceive of such evil coming from our own government. It took the Podesta emails to explode my little world. 15 years after 9/11. In the future, you will be their rock.
