Deranged Minneapolis g::unman Robin Westman blamed his mother for his decision to k!ll “so many people” at a Catholic school after she warned him that he would regret tr@nsitioning to female — while in the next line in his manifesto, he discouraged people from letting their kids change gender.

In his disturbed manifesto, Westman, 23, claimed to be anxious about a visit from his mother in an entry dated July 1, where he recalled her concerns about him tr@nsitioning.

“Your words, mother, made me stay in my discomfort unable to ask for help to avoid admitting defeat. You were right mama, but the way you handled it led me to wanting to k!ll so so many people,” he wrote.

In the rambling writings, the crazed g::unman also appeared to blame tr@nsitioning and smoking marijuana for his violence.

Much of the manifesto is written in a homespun code that uses Cyrillic characters and English phonetic words, which have been tr@nslated by The Post.

Here’s what we know about the Catholic school sh00ting in Minneapolis

Students had begun their first week of school at the Annunciation Catholic School in Minneapolis, Minnesota, two days before the sh00ting.
Robin Westman, a 23-year-old tr@ns woman, opened fire through the stained glass windows on Wednesday morning during a celebratory back-to-school Mass filled with children.
The sh00ting k!lled two children and injured at least 17 others, before Westman di3d of a self-inflicted gu::nsh0t wound.
Westman had written “k!ll Donald Trump” and “for the children” on gun magazines, and posted videos of a handwritten manifesto.
Westman’s mother had worked at the school.

The July 1 entry included second thoughts Westman was having regarding his gender and worries about what would change during the meeting with his mother, Mary Grace Westman.

“When I was first out to my mother, she was VERY antagonistic. She really made me hate myself and think I will never be good enough,” Westman wrote.

“I remember one day, she said something like, ‘In the future you will look back and feel ridiculous about who you feel like you are inside. You will regret this.’

“Well guess what mom?! I regret being born,” the g::unman added.

Mary Grace had signed Westman’s legal name change in 2020 —  from Robert to Robin — in apparent support of his gender-identity change. Westman was 17 at the time.

Mary Grace, who once worked at the Annunciation Catholic Church school that Robin graduated from, is now speaking with police after previously refusing to cooperate with the investigation into why her long-troubled, hate-filled son unleashed the heinous attack at his alma mater, investigators said.

“I can tell you this, through working with our partners with the Bureau of Criminal Apprehension of Minnesota there has been conversation, and I am not at liberty to go any further than that,” Minneapolis Assistant Chief Christopher Gaiters said during a press conference Friday afternoon.

The mom has retained criminal defense attorney Ryan Garry, according to Fox News.

Despite the antagonistic feelings displayed in the manifesto, Westman penned a separate letter to his family and friends telling them how much he loved them and how his parents shouldn’t blame themselves with how he turned out.

“You did not fail me, you gave me so much. I truly appreciate the love you have given me,” Westman said to his parents. “I feel I was raised to be a good person.

“I’ve kept those traits of empathy, self-sacrifice, and good character. Please do not think you have failed as parents,” he added.

He admitted in a series of disturbing online videos that he regretted being brainwashed into “being tr@ns,” and planned to cut his long hair before unleashing his carnage, in which he planned to k!ll far more kids.

Westman also wrote that he could neither stop smoking — which he suspected without apparent evidence had given him cancer — nor the attack that claimed two lives and left 18 others wounded at the Annunciation Church on Wednesday.

“I wish I could stop vaping but I can’t! If I could stop vaping, I could stop myself from doing this attack, but I just don’t want to. Stopping vaping will not get rid of my cancer, nor will it make these fantasies go away.”

The twisted g::unman eventually put his plan into motion on Wednesday, when he opened fire through the church’s stained glass windows during morning Mass, k!lling an 8-year-old Fletcher Merkel and 10-year-old Harper Moysk.

Westman unloaded 116 rifle rounds and turned the gun on himself before authorities could reach him.
