Funeral expenses and help transitioning

On November 17th we unexepedly lost my father, Gary. Dad devoted his adult life to serving in the United States Navy as a Machinist Mate and in the Army National Guard as a Motor Transportation Operator. Dad was best described as a man with a hard exterior, but a heart of gold. This was best displayed when it came to his grandchildren. To put it blunt, he was a hardass, but the minute his grandchildren needed wanted or needed anything, Grampy would turn into the biggest teddy bear. My father was the sole provider and handled all of the finances in the home. With the unexepedness of his passing, funeral costs, home expenses, and attempting to providing some "normalcy" during the holidays, I am asking for any help that can be provided to alleviate some of these issues during these hard times.
