My hope is that they had all been called by God in his own perfect timing.
I want to keep this short and say that if you have lost a loved one then you can in some church's attend a seperate group called Beaverement Cafe. This is run by trained people who do this who have DBS checks. Jesus said Blessed are those who mourn and those who are poor in spirit. We need to be there for them, but also encourage them think of the future to.
There is also spiritual conselling which is low cost or free where you can talk about your distress. God sees the plight of the afflicted. You can search to for a spiritual companion. The Holy Spirit can work with you to deal with trauma to help you try and move on. Trauma can lead to problems in the holistic body. The link below is just one place to look for such support.

Check on those who you care about who are dealing with grief if you can in the spirit of Jesus' law, when I needed a neighbour and being there for others to lend a hand. As Christians we should build each other up and encourage each other as said so clearly in (1 Thessalonians 5:11). "Wherefore comfort yourselves together, and edify one another, even as also ye do" .(Galatians 6:2) speaks to us also about the need to support fellow Christians.
I will also say that that the prayers of a loved one said in true faith can save those in the household to the next life as the Bible tells us-(Acts 16: 32-24) "And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house." Shortly after their mortal death still try and save a loved one if they didn't have a strong faith-You have nothing to lose by trying if you are a believer.
