WASHINGTON – The shutdown provoked her meltdown.

The official stenographer who flipped out on the floor of the House as the world watched the vote ending the nation’s debt-ceiling crisis was clocking mind-numbing hours during the government shutdown, her husband said.

Dan Reidy told The Post Thursday that his wife, Dianne, was plagued by sleeplessness since the start of the shutdown Oct. 1.

“Two weeks, waking up in the middle of the night. She’s like, I can’t sleep, God’s got me in the work,” Reidy said, speaking from the living room of the couple’s Maryland home, where they’re raising two twin girls.

“God was preparing her for this vote last night, because this was kind of the culmination of everything,” he continued.

“This was the big one. Everybody’s there. And Dianne didn’t know what she was sharing, she didn’t know when — but she just sensed in her spirit.”

Dan Reidy, a former associate pastor of a Christian church in Florida, denied that his 48-year-old wife has mental problems.

He said she doesn’t drink, smoke or take medications — and that he accepted her claim that she was acting as a messenger for God.

Dianne Reidy was present sporadically during the half-hour interview, but spoke only briefly towards the end.

“I’ve never felt better,” she said, “I’m glad that I fulfilled God’s mission for me, absolutely. It lifted a tremendous burden. It was a very hard burden to carry as you can imagine.”

The minivan-driving mom worked multiple late nights during the 16-day shutdown, by her husband’s account.

Late Wednesday night, as the 16-day was ending, she approached the House dais and suddenly yelled: “The House is divided” and “this is not one nation under God – it never was!”

Security pulled her from the chamber.

Her husband said Reidy plans to return to work Tuesday – though they haven’t heard from her employer, the Clerk of the House.

“She went through, ‘There’s no way I’m doing this’ over two weeks to: ‘God can we get it over with?’ So she had submitted basically at that point,” Dan Reidy said.

His wife has worked at the Capitol for more than eight years, and has been a stenographer for almost two decades, also working in D.C. courts.

Reidy described his wife as someone enamored of the “decorum” of the House – where arcane rules proscribe who can address the chamber and in what manner, and where stenographers silently transcribe every utterance.

Asked whether she loved the House, Reidy responded, “I did, yeah.”

Pressed on whether she still loves it, she replied: “No, not any more. Since it just got real toxic” — then abruptly ended the interview.

After her bizarre behavior , she was taken to George Washington Hospital and spoke to a psychiatrist, then released.

“The doctor was asking what was the message, what was the intent of the message?” her husband said.

“She goes: `I don’t know I just spoke what I felt God was putting in my heart. I don’t know who it was directed at’.”

Dan Reidy described himself as a Pentecostal Christian who believes strongly that God can communicate through individuals He said it was the second time God had communicated through his wife.

He said her colleagues know of Dianne’s faith, but that she’s not “in-your-face” about it.

“It’s just so totally out of character,” he said of his wife’s outburst on live TV.
