The fashionista who jumped to her death from the George Washington Bridge felt under siege by five frenemies she barred from her funeral via suicide note — including one who told her to overdose, The Post has learned.

“Go try to kill yourself on Xanax again, you unstable loser. Go f--k yourself and never speak to me again,” Alison Tinari wrote in a Facebook exchange with troubled Ashley Riggitano, who killed herself Wednesday, her 22nd birthday.

The blond beauty left behind a multipage, handwritten note in a Louis Vuitton bag that excluded Tinari and four other women from the funeral because of their contentious relationships through the years.

A source identified the others as Teresa Castaldo, Beth Bassil, Victoria Van Thunen and Samantha Horneff.

Van Thunen was Riggitano’s business partner at Missfits, a jewelry-design business. Castaldo and Bassil were classmates at Midtown’s Laboratory Institute of Merchandising, and Horneff was a friend from New Jersey.

Riggitano placed her handbag on a walkway at about 4:40 p.m. Wednesday before leaping from a midway point in the Jersey-bound lanes of the upper level, authorities said.

Prescription drugs, including Adderall, which is used to treat ADHD, and Klonopin, an anti-panic drug, were found in her bag.

Riggitano’s suicide notes — written in girlish cursive on lined, loose-leaf paper — revealed the depths of her despair.

“To any funeral, these people should not be allowed based upon words and actions,” she wrote about the five women.
