What is the meaning of the song There's no sympathy for the dead?

Well, I always think of it as his drug addiction caused by being abandoned by his mother. "I have the remedy for love, I struck the glass, it broke the bones inside my fist but I'm okay" meaning he tried the drugs as his remedy and got addicted. A lot of people say its a love song about him breaking up with a girl, but there's many clues in the whole song about drugs and his mom.
