Sorry to hear, but there is hope.

1 Thessalonians 13-14
13Brothers, we do not want you to be uninformed about those who sleep in death, so that you will not grieve like the rest, who are without hope. 14For since we believe that Jesus died and rose again, we also believe that God will bring with Jesus those who have fallen asleep in Him.

I lost a sister when she was 27 to head on collision caused by a drunk driver, killed both the drivers and a passenger in each vehicle. Tragic, four lives instantly gone.

Grieve for a time, stay strong.
