The 26-year-old Canada-based comedian said her new documentary, which will have an appearance by Dwayne "The Rock" Johnson, chronicles her world tour journey and life, reported Entertainment Weekly.
"It's very close to my heart. It's a story about me going through the trials and tribulations of my life, and really making the decision to be happy," she said
Singh, who has more than 6 million subscribers on YouTube, said she made the documentary as she wanted to communicate to a larger audience.
"I wanted it to be in this fashion of storytelling where you could come on a journey through my life framed through my tour... The type of film this will be is a very no-barrier, no-holds-barred me being very honest with you, me talking about depression and overcoming that."
"A Trip to Unicorn Island" is expected to release soon.
