Amy (Duggar) King‘s final wedding dress fitting was supposed to be a joyful moment for the reality star, but her happy day was cut short when her cousin Josh publicly confessed that he cheated on his wife Anna and had an addiction to pornography.

“I was completely shocked just like the rest of the world,” Duggar posted on her blog on Monday.

“The only difference was I was being fitted for my wedding dress with tears running down my face and a glass of wine in my hand as the news broke. I wondered what the heck was going on? A million questions flooded my mind.”

Just months before Josh’s admission in August, a 2006 police report revealed that he had also been accused of inappropriately touching five minor girls as a teen.

“Life was just wonderful drum roll please .” Amy wrote. “Until one of my family members made some terrible confessions. I knew nothing of the molestation charges.”

Shortly after his announcement Josh, 27, flew to a faith-based rehabilitation center in Rockford, Illinois, where he is currently still receiving treatment, says Amy.

“Rage came over me, sadness crept in, and reality sat in that the person I had known my entire life turned out to be a fraud, and a complete stranger,” she recalls of the scandal.

“I’ve always heard that there were people in this world that lived a double life, but I never thought that someone so close to home would be living a lie.”

While Josh’s parents Jim Bob and Michelle released a statement asking for prayers for Josh and their family, Amy’s opinion on the scandal is simple.

She told PEOPLE exclusively on Monday after releasing her blog: “I hope he gets the help he needs.”
