If you're not a fan of Donald Trump, the chances are the past week has not been an enjoyable one.
Many who did not vote for the president-elect have decided to protest against the new prospective leader of the USA, and large groups of the population are concerned that the businessman will roll back years of Barack Obama's hard work on climate change, LGBTQ rights and more.
For those concerned, however, we've compiled some inspirational and amusing quotes from Obama to help you through this time.
"Through every victory and every setback, I've insisted that change is never easy, and never quick; that we wouldn't meet all of our challenges in one term, or one presidency, or even in one lifetime." - The Democratic National Convention, 2016.
"I tease Joe (Biden) sometimes, but he has been at my side for seven years, I love that man. He's not just a great vice-president, he is a great friend. We've gotten so close in some places in Indiana, they won't serve us pizza any more." - The White House Correspondents' Association Dinner, 2015.
"One voice can change a room. And if it can change a room it can change a city, and if it can change a city it can change a state, and if it can change a state it can change a nation, and if it can change a nation it can change the world. So I just have one question for you New Hampshire: Are you fired up? Ready to go?" - An election rally in New Hampshire, 2016.
"As some of you heard, the state of Hawaii released my official long-form birth certificate. Hopefully this puts all doubts to rest, but just in case there are any lingering questions, tonight I'm prepared to go a step further: Tonight for the first time, I am releasing my official birth video." (The Circle Of Life scene from The Lion King plays on the big screens.) - The White House Correspondents' Dinner, 2011.
"The America I know is full of courage, and optimism, and ingenuity. The America I know is decent and generous." - The Democratic National Convention, 2016.
"I've even let down my core constituents: movie stars. Just the other day Matt Damon - I love Matt Damon - said he was disappointed in my performance. Well Matt, I just saw The Adjustment Bureau so right back atcha buddy!" - The White House Correspondents' Dinner, 2011.
"If you're walking down the right path and you're willing to keep walking, eventually you'll make progress." - A campaign rally in 2008.
"Actually I think it's a good idea (being limited to two terms). If I ran a third time it'd sorta be like doing a third Hangover movie. Didn't really work out very well, did it?' - On Between Two Ferns with Hangover star Zach Galifianakis.
"The arc of the moral universe is long, but it bends towards justice." Not an Obama quote, but one he is keen on. The quote is on Obama's office rug, and is attributed to Martin Luther King, although it was said originally by Theodore Parker, a 19th century abolitionist.
"We've got the bright new face of the Democratic Party here tonight, Mr Bernie Sanders! Bernie, you look like a million bucks. Or to put it in terms you'll understand, you look like 37,000 donations of $27 each." - The White House Correspondents' Dinner, 2016.
"Where you are right now doesn't have to determine where you'll end up." - Back to School event, 2009.
Right on, Barack. Right on.
