The "Bodyguard" actor, who had a meltdown on the show, said he lost focus from 'Bigg Boss' too early as he slipped into depression and sleep apnea.
"I overrated myself for the show. I didn't have a clue that life will be so tough inside the house for a person like me who is overweight. I overlooked certain protocols of the house before entering into it," Rajat told PTI.
But the actor, who will be remembered for his funny T-shirts, promises that people will get to see a new Rajat during the finale of the Colors show in December.
Rajat denied claims made by some of co-contestants Armaan Kohli and VJ Andy that his meltdown was a publicity stunt to gain prominence on the show.
"I entered the house with much enthusiasm and got along well with everyone. I participated to entertain everyone on the show but that doesn't mean that I am a joker. I am sorry that I couldn't meet the expectation of my fans," he said.
