“Everyone isn’t going”
Truth God when people leave because in most cases it’s for your good so you can grow and be all that God will have you to be. Ask God to forgive you for being angry and thank he, for in Jeremiah 29:11 it say “For I know the plans I have for you, “declare the Lord,” plans to prosper you and not to harm you, plans to give you hope and a future.
And always remember
God says ,”He will never leave you or forsake you.”

There is peace in his word.
