I know how you feel, I found out when I was right in the middle of writing the final chapter of my 'Darkest knight' fic and I just stopped. I closed the laptop and haven't touched it since.
I'm just thankful that I was there to see a group of average dudes from New Jersey become one of the all time greatest bands the world has ever seen and how they became the voice of the misfit generation. We were there and we should all be thankful although I have cried about it.
We'll be patient xoxo

I've cried all throughout this weekend :( But I agree. As Dr. Suess said, "Don't cry because it's over, smile because it happened."
