“Danny … I’ll see you later,” the mom of young suicide victim Danny Fitzpatrick poignantly told him at the boy’s funeral Mass on Wednesday.

The tragic 13-year-old hanged himself in the attic of his Staten Island home last week — the victim, his parents say, of relentless bullying and heedless school administrators.

“From the moment he was born, he was a saving grace to our family,” his mom, Maureen, told 500 mourners gathered under the vaulted ceiling of Sacred Heart Roman Catholic Church.

“I just want to thank God for giving me the gift of being able to give birth to such a beautiful angel,” the mom added, as her husband, Daniel, and their three adult daughters listened.

“I pray that his soul is at peace and the darkness that was inflicted on him by others and caused him so much pain and sorrow is gone,” she added.

“Danny, your mother loves you with all heart and soul,” she said. “I’ll see you later … and I thank God for giving you to me.”

The boy was “the glue to our family,” his sister Eileen, 24, told mourners. “He was everyone’s favorite. We would have gone to the ends of the Earth for our brother Danny.”

The funeral procession was led by the father’s motorcycle club, Rolling Thunder, en route to St. Peter’s Cemetery in Staten Island.

Officials at Holy Angels Catholic Academy in Brooklyn have insisted that they did everything possible to help the troubled boy. Family members counter that administrators turned a deaf ear.

“You get paid, and not say something?” the father said of administrators in a video posted to Facebook on Wednesday morning.

“Shame on you. Shame on you. Really, I mean, why in God’s name did you become teachers in the first place, so you can have summers off?”

The family is asking Sens. Chuck Schumer and Kirsten Gillibrand to sponsor a “Danny’s Law,” which would strip teachers and administrators of their licenses if they fail to help a bullied child, and hold the parents of bullies financially responsible for victims’ medical and funeral expenses.
