Depression is a killer, it's a mental illness. It leads a person to believe life is **** and not worth living, desperation, daily sorrow, once you start down that road of thinking the emotions just get worse and worse until your finally suicidal! I went through it for years in my early 20's. But what Brad didnt know is he could have gotten out of it with therapy, maybe medication, different way of thinking which takes time and practice. A depressed person just gets into that negative way of thinking and they dont even realize they are doing it. One problem can seem like the end of the world especially with relationships or members of the opposite sex. Brad was tortured over his relationship with his fiance, band and tour issues, family problems, etc. It's normal everyday stuff but for him it was the end of the world!
