I had to medicate myself before I could even think about getting in the car.

When asked about his lowest point, Barker spoke about being on tour in Australia in 2004.

That was pretty pathetic.

My bones were so brittle from so much painkiller use, he said.

And I wasnt proud.

I had to call [Blink-182 member] Mark [Hoppus] and say, Hey, man.

Im like borderline suicidal.

I need to go home.

Like not even one show had started.

Id been there two days.

I hadnt slept one day.
