After both cheated death in that fatal airplane crash last year, Travis Barker is struggling to accept the loss of his good pal Adam Goldstein.

"Don't know how I am gonna play 2night but I am for AM," the Blink-182 drummer, 33, posted on Twitter Saturday night before the band's concert in Hartford, Connecticut. "My brother is gone. I love u and miss u, I'll never forget all the good times we had."

"I'll never forget everything we've been through and every time I play the drums, I'll think of you. U were an amazing friend/DJ/human being."

"Rest in peace, my brother," he Tweeted. "This really f*cks me up."

Later that night at the concert, Blink's bassist Mark Hoppus told the crowd, "This night is really hard for us on stage. We lost a dear friend yesterday. His name was Adam Goldstein. You probably know him as DJ AM. He was an innovator and a genius and he loved music more than anything else. Above all he was a dear friend."

The band dedicated their song "Down" to AM, and the guys members cried as it played. Travis didn't talk to the crowd at all and actually left the stage before the concert was over.

"Thank you very much," Mark said at the end of the show. "Although today is one of the hardest days in our entire lives, we wouldn't want to spend it anywhere else. Thank you for all of your support."

I can't even imagine what Travis is feeling. My heart hurts for him.
