Peace, Strength and the Grace of God be with you and yours in this time of sorrow. I would encourage you and the family to consider attending some sort of 'Grief group' through a church or other civic organization. Not necessarily right away and probably not even all you going at the same time but consider it.
I attended one at my church after my wife passed away from natural causes. It was very helpful to me just to know that I wasn't the only one out there whose emotions were like a giant bowl of spaghetti and that what I was feeling was not unusual. I even eventually helped to lead later groups.
At one of our groups, there was a mother and daughter. They had lost a daughter/sister to a drug OD. Their responses to the loss of the same person were quite different. Even though it was the same person they lost, the relationship was different. Please keep that in mind as you and the rest of your family move forward with your own lives.
