Paul, 22, has repeatedly accepted the blame for the video in question. "It's not like I'm a bad guy. I am a good guy who made a bad decision," he said.
"It's been tough, cause ironically I'm being told to commit suicide myself," he revealed. "Millions of people literally telling me they hate me, to go die in a fire. Like, the most horrible, horrific things."
Paul said he deserves the criticism and the blame for what he did.
"This has been, to be honest with you, the hardest time in my life," he said. "I think I'm going to earn a second chance. I don't think everyone should get a second chance. Some people do horrible things ... this was a horrible lapse of judgment. And I can, will and am going to learn from it and be a better person."
After a self-imposed hiatus, Paul returned to YouTube last week with a heartfelt video that focused on suicide prevention, including an interview he conducted with a man who had attempted suicide.
"I've gotten to meet the most incredible people and have the most incredible conversations," Paul said on "GMA." "And, in fact, that's one thing I don't regret about this whole experience is I would've missed out on making these relationships and getting this education."
"I know I've made mistakes, I know I've let people down," Paul said. "But what happens when you're given an opportunity to help make a difference in the world."
Paul said he's "trying to grow as a human being" and has pledged $1 million to various suicide prevention organizations.
YouTube removed Paul from Google Preferred, a premier ad service that offers brand advertisers access to top channel producers, after the backlash.
The company also said Paul would not be featured on Season 4 of the original YouTube series "Foursome" and added that "his new Originals are on hold."
YouTube previously released a statement on its Twitter page indicating Paul would be penalized for sharing the inappropriate video with his 15 million subscribers.
“The channel violated our community guidelines, we acted accordingly, and we are looking at further consequences,” the statement said.
On "GMA," Paul said he understands what Google did and "while I don't necessarily maybe agree with it, I do respect it. I do respect it."
Paul has taken to social media and other online platforms to apologize repeatedly this year.
On Jan. 1 he wrote a letter to fans, saying he posted the controversial video to raise awareness of suicide prevention and never intended to anger anyone.
He later followed up with a video apology, and then on Jan. 3, he tweeted, "Taking time to reflect. No vlog for now. See you soon."
"I will think twice in the future about what I post, probably three times, four times" or more," he said.
