A Twitter user believed to be a student at the Florida high school where 17 people were slaughtered slammed President Trump on Thursday for his social media response to the massacre in a tweet that has since gone viral, according to a report.

“I don’t want your condolences you f–king price (sic) of s–t, my friends and teachers were shot. Multiple of my fellow classmates are dead,” the user, “Sarah,” posted under @chaddiedabaddie.

“Do something instead of sending prayers. Prayers won’t fix this. But Gun control will prevent it from happening again,” she added in her comments, which as of early Thursday were retweeted 163,720 times.

The tweet purports to come from the account of a 16-year-old student at Marjory Stoneman Douglas High School in Parkland, according to Mediaite.

After the shooting, the president tweeted “prayers and condolences to the families of the victims,” adding that “no child, teacher or anyone else should ever feel unsafe in an American school.”

On Thursday, he suggested that people who knew the suspect — former student Nikolas Cruz, 19 — should have alerted authorities about his troubling behavior — including jokes about taking out his classmates, as one student said.

“So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior,” Trump tweeted.

“Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again!”

The girl described Wednesday as “the worst day of my life.”

“I’ve been crying helplessly for hours. Thank you to everyone for your support. I’m going to try to sleep now. #DouglasStrong,” she tweeted.
