Rebuild our life after a horrible shooting

I'm a single mom trying to rebuild after a senseless act of violence struck our lives. Police said the boy's mother, Sasha Lowe, told them she was driving to their home in the 5300 block of Garfield just before 10 p.m. when she saw two men shooting at someone. Her youngest son, Shamar, was hit in the head by gunfire Except the Lord build the house, they labour in vain that build it; except the Lord keep the city, the watchman waketh but in vain. Psalms 127:1 KJV
