Patton Oswalt writes moving Facebook post about grieving his wife

Michelle McNamara, writer and wife of Patton Oswalt, died in April.

(CNN)Patton Oswalt wrote a moving tribute about the loss of his wife, Michelle McNamara, and his struggle with grief on Tuesday.

"Thanks, grief," Oswalt wrote on Facebook. "Thanks for making depression look like the buzzing little bully it always was. Depression is the tallest kid in the 4th grade, dinging rubber bands off the back of your head and feeling safe on the playground, knowing that no teacher is coming to help you. But grief? Grief is Jason Statham holding that 4th grade bully's head in a toilet."
Oswalt explained that grieving for his wife over the last 102 days has been incredibly difficult, but he has been shown "humanity and grace and intelligence" from supporters.
    "Complete strangers will send you genuinely touching messages on Facebook and Twitter, or will somehow figure out your address to send you letters which you'll keep and re-read 'cause you can't believe how helpful they are," he wrote.
    Oswalt's wife, McNamera, who was a crime writer, died suddenly in April at the age of 46.
    Oswalt also paid tribute to his late wife in a column he wrote for Time magazine in May.
    He ended Tuesday's Facebook post on a hopeful note.
    "I'm going to start telling jokes again soon. And writing. And acting in stuff and making things I like and working with friends on projects and do all the stuff I was always so privileged to get to do before the air caught fire around me and the sun died," he wrote. "It's all I knew how to do before I met Michelle. I don't know what else I'm supposed to do now without her."
