After being hospitalized for a month due to kidney and liver failure, Sum 41 frontman Deryck Whibley, 34, has emerged from the hospital, looking shockingly frail. TMZ caught a snap of Whibley leaving the hospital, which you can see below.

In a recent update (released along with some shocking images of the singer in the hospital), the Grammy-nominated Canadian musician revealed that he had a hardcore drinking problem and said, “If I have one drink, the docs say I will die.” The singer’s condition answered the questions of many fans, who were wondering about the delay with Sum 41.
