Amebix - Not really, Adam's Song is more of an anti-suicide song...but I could see how it doesn't sound that way since it's written in the form of a suicide note. The writer was inspired by a teen suicide letter he read in a magazine, and also the loneliness and depression he was facing at the time. But the song ends with more hopeful lyrics - instead of continuing to reflect on the past, it talks about the future and having a better outlook.
Mark Hoppus (the writer) said, "But "Adam's Song", the heart of the song is about having hard times in your life, being depressed, and going through a difficult period, but then finding the strength to go on and finding a better place at the other side of that." He made this comment after making a statement about a teen that killed himself with the song playing on indefinite repeat.
I know you didn't ask for all that. I just felt the need to explain. I'm sorry if I annoyed.
