Patton Oswalt is confronting his tragic year the best way he knows how.

The Ratatouille star expressed his grief over the loss of wife Michelle McNamara -- who died in April at age 46 -- as well as his malaise for America following the bitterly contested 2016 presidential election, in an emotional, cathartic stand-up set over the weekend at Los Angeles' Largo comedy club.

The gratitude was in response to a fan, who wrote, "Wow. @pattonoswalt's set was deeply honest, hysterical, moving, oddly comforting for weird, bad times. Nice having someone like him around."

Earlier in the day, Oswalt tweeted about not wanting to celebrate his heartbreaking year.

"I'm going to bed at 9pm on New Year's Eve. Not celebrating s**t. 2017 has to EARN us celebrating it. We made 2016 too complacent," the comedian tweeted.
