It is known that 2015 has been a difficult year to be a One Direction fan. (I won't revisit the depressing details for you here, because you've lived the pain, you know what I mean). 

But on Wednesday, it was time to put all of that aside to celebrate a very important milestone. The day marked the five year anniversary of the official formation of the band. It's hard to imagine now, but five years have came and gone since Louis Tomlinson, Harry Styles, Niall Horan, Liam Payne, and Zayn Malik became the heart-stealing group known as One Direction. Fans all over the world celebrated with the hashtag #5YearsOfOneDirection and Harry took notice,  posting a series of tweets that thanked fans for their support.

'We have been a band for five years. And it is impossible to thank anyone enough for all the support they have given us over this time,' Harry said. 'All the crew that we have been so lucky to work with, and everyone who is behind the scenes. We thank you for everything that you do. To you who support us, in any way, thank you. We wouldn't be here without you. You did this and we thank you for having us. All the love.'

Daddy-to-be (sorry I know I promised I wouldn't bring up any sore subjects) Louis Tomlinson alsothanked fans on Twitter. 'Every single day we are thankful for the platform that you incredible people gave us ,' he said. 'What an amazing 5 years it's been!!'

Thanks guys for understanding how utterly exhausting it's been to love you and your band this year.  On the bright side, we're about halfway through 2015, so hopefully the worst is behind us and we can just focus on the important things. No matter what happens, we'll always have our memories, guys.
