Like most fans of Girls, the end of the HBO show has turned Allison Williams into an emotional wreck. While playing Marnie Michaels on Lena Dunham's hit series, Williams navigated ill-fated relationships, ill-advised weddings, and some ill-advised motorboating, all of which she's saying goodbye to now that the show is coming to a close after six years. The actress included a heartfelt caption about her final day of shooting with an Instagram photo of her looking heartbroken from season five's excellent "The Panic in Central Park" episode. "How I'm feeling right about now," she wrote. "Today is my last day playing Marnie Michaels. Six years of passive aggression, folded arms and eye rolls...but also bravery, fierce protectiveness and ambition. I've loved you well, Marn. 💕💕 #WhatIAm #MarnieMarieMichaels." If it's any consolation, the photos from the set of Girls that came out over the Summer hinted at a possible happy ending for some of its characters, so fingers crossed Marnie gets one, too.
