Melissa Rivers Reflects On Second Mother's Day Without Joan Rivers

— -- Still coping with her mother's death, Melissa Rivers, the only daughter of the late comedienne Joan Rivers, who died in September 2014 at age 81, knows Mother's Day could be an agonizing time.

The "Fashion Police" host, who stepped into her mother's shoes to lead the show after her death, recently opened up in a blog post about Mother's Day, calling it a "nerve-wracking holiday," and revealed her therapist's tips for getting through Sunday.

"This will be the second Mother’s Day since she died," Rivers wrote in a blog post titled, "My Therapist Told Me to Journal," "and while the loss has been profound, I’ve filled the giant space in my life she occupied with other things, like grief, anger, fear, and Xanax. And work."

"I’ve been busy, busy, busy, throwing myself into lots of projects: 'Fashion Police,' writing books, and developing TV shows," she adds. "The only thing I haven’t been working on is myself."

To help her through the grieving process, Rivers said that at the suggestion of her friends and family, she decided to see a therapist, who suggested she keep a journal.

And although she was initially hesitant -- especially in the age of tabloid media -- it was her mother's life that inspired her to give it a try. Joan Rivers also kept a journal, which formed the basis of her 2014 memoir, "Diary of a Mad Diva," Rivers added in the blog post.

A mother herself, she also quipped about what she'd like from her 15-year-old son, Cooper, on Sunday.

"All I want for Mother's Day is 24 straight hours without him scowling, rolling his eyes, or making dismissive sucking sounds at me with his tongue," she said. "We'll see what happens."
